This option allows you to specify another directory from which to load rules files. I'm seeing this in https://github.com/enzyme-js/enzyme, while editing basically any file. Would you be able to distil a reproducible case or share the project with me using another channel than a public GitHub repository? I have not found any info about this plugin on the Internet, not even on the github page, so I'll explain a little bit what you will find: It adds a new label in options -> editor -> html5/js called 'eslint' to set the path to eslint and to the configuration file you want to use. Did you consider filing this against ESLint or one of the used plugins? Can be a file or a directory. Can you then provide me with the call stack. My first guess is a specific setting we have but I haven't been able to find anything that would cause it in our config files etc. The file will be created in the directory where the eslint command is executed. Let’s start by adding the eslint plugin for prettier by executing the below command: npm install -D eslint eslint-config-prettier. 3 errors and 0 warnings potentially fixable with the `--fix` option. In some project we have several eslintrc files - In my project at HPE Live Network, we have four eslintrc files: One for the server (node.js), another for the server spec files (mocha), third one for the client (angular) and the fourth one for the client spec files (karma + Jasmine). Now, to make the actual migration simpler, run the tslint-to-eslint-config utility. ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code, with the goal of making code more consistent and avoiding bugs. It seems to happen reliably for me when I start up the editor and when create a new file in a project that has circular depedencies. For that we need to install eslint extension first. There will be a pause of a few seconds while Package Control fetches the list of available plugins. I will look into providing a reload command. 复现错误的步骤. I've to say I'm the only one of my team having the issue for now (also the only one using Windows), although we're several to use VSCode. I've having the same issue on a couple of repositories regularily. This tool will take your TSLint configuration and create the "closest" ESLint configuration from it. Problem found. The problem is that sometimes, especially when we change a lot of code or change one the eslint rules, there are a lot of errors. I can't remember exactly what my previous configuration in my settings file was, though something similar to what the OP pasted. @dbaeumer I have a repo where this can be reproduced: https://github.com/Goldziher/dtsgenerator. Legend Indicates that the rule is fixable, and using --fix option on the command line (opens new window) can automatically fix some of the reported problems. I will then see what additional information we can obtain to be able to reproduce this. There will be a pause of a few seconds while Package Control fetches the list of available plugins. Among the entries you should see ESLint Fix. Please use Package Controlto install the linter plugin. Command Palette. Unfortunately, this is not a part of ESLint I'm very familiar with so nothing is jumping out to me. For example, the Vim plug-in will run something like the following: eslint -c --fix Show more Maintaining a strict code standards and enforcing those by using tools like PHPCS, jshint, eslint and other tools is critical for any successful continuous integration process. If an .eslintignore file is not found and an alternate file is not specified, ESLint will look in package.json for an eslintIgnore key to check for files to ignore. I forked this package and made some updates to the eslint config. Step 1: Install ESLint Extension for Visual Studio Code. If a problem is found, Husky will stop the process and commit will fail. This will ensure that the plugin will be updated when new versions are available. -bash: eslint: command not found. One way to quickly add them to the project is running the command on the terminal. Removing one solved the hanging issue but I couldn't find a way to get both to work together. ESLint. Any more steps you can provide (e.g. about 4 years eslint runs in command line but files are not linted in atom; about 4 years Error: EPERM: operation not permitted, write; about 4 years Other eslint filetypes; about 4 years Installing “linter-eslint@7.3.1” failed. Sign in See our, is critical for any successful continuous integration process, The ruling party in Israel in primaries…, The fake SMS, The Israeli primaries and the…. to your account. It shows that the linting hangs in the ESLint npm library. Have a question about this project? But I have to say I didn't make any meaningful changes. I can provide steps on how to do this. I got a performance regression after an update of VSCode insider, not sure which version was working fine, updated on 08.26.2020 - 08.27.2020. After locating the global eslint module directory, go to your project directory and locate the eslintrc file. @reifnotreef can you share that repository with steps to reproduce? (Don't know the internals of this plugin to know if there's a possibility for this.). Figure 2. This website uses cookies to improve service and provide tailored ads. @NicolasBuecher I would still like to understand why this is happening for you. BUT, VSCode doesn't lint anything: Then, when I update settings.json to format and/or autoFix on save: Now I systematically get the never ending pop up (and still the same output in ESLint console): If somehow it can be useful, here is a part of the package.json of the repo: Here is all I have, sorry for not introducing any new elements to help us. Unfortunately no, it's a private work repo. It would definitely throttle my CPU and I'd always have click "Cancel" where it would skip the auto-formatting and then save the file. VS Code version: Code - Insiders 1.49.0-insider (6384e3246884694cbc34eacc70281ada15e2c7f2, 2020-08-28T16:02:16.834Z) Highly appreciated. I had this issue today, which I believe was triggered by me importing an enormous javascript data file (>3MB). I wonder if that could be related to that issue, because I had - while watching this behavior over the weekend - the feeling it happens more often when it's trying to reformat (prettier via eslint) in a state, where the code is not actually parseable. I put some dirty code in a file and when I run: I get exactly what I'm expecting from the linter: So I guess eslint works fine. 排查错误的原因 I'll try to play with VSCode and ESLint versions. which file to save and what to type beforehand). ESLintis a linting tool created back in 2013 by Nicholas C. Zakas and is currently the most powerful and extendable linter available for JavaScript. The text was updated successfully, but these errors were encountered: Without a reproducible case this is very hard to track down. If that command is not highlighted, use the keyboard or mouse to select it. I am not sure what the ESLint extension can do about this except offering a command to reload ESLint. @mysticatea any ideas? This flag only enables environments; it does not disable environments set in other configuration files. I looked at the case and I can confirm the slowness. Almost all cases I have seen so far result in high CPU usage in the eslint npm module itself. Details about the global variables defined by each environment are available on the configurationdocumentation. A great introduction on how to lint TypeScript using ESlint can be found in the TypeScript - ESLint. The text was updated successfully, but these errors were encountered: eslint bot added the triage label Jun 19, 2018. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Suddenly, you run npm run lint and it shows quite a lot of linebreak-style errors. Sorry, haven't had the time to really debug it, but maybe @myasonik this can help reproducing this. Please make yourself familiar with the introduction before using the VS Code ESLint extension in a TypeScript setup. The --fix flag is allowing eslint to autofix everything that it can autofix. Not an expert in the code. In this tutorial, you will set up ESLint on Visual Studio Code and implement a custom configuration to deal with log statements in debuggin Already on GitHub? I am so far always using the "Developer: Reload Window", but only reloading eslint would be nicer. Does anyone know why the validation of a file in ESLint needs to load a webpack configuration file. I must add them to eslintignore. ESLint uses an AST to evaluate patterns in code. Install ESLint on your computer. @sepehr500 in this setup do you see a slow down when running eslint in the terminal? Allows to have different versions of ESLint for different projects; Does not hide the ESLint dependency. No it's not, there is only one package.json file at the root. I am not sure what the ESLint extension can do about this except offering a command to reload ESLint. Just opening that project and trying to save a file a couple of times, usually from around the 5th saving on it'll always be in that state where it's stuck in the "Getting code actions from ESLint" phase. Especially make sure that you can validate TypeScript files successfully in a terminal using the eslint command. @dbaeumer Unfortunately I can't share the project but let me try with debug info. Here are the steps: When you hit the problem go back to the first instance of VS Code. This directory is in: Windows: C:\Users\USER\AppData\Roaming\npm\eslint, Linux\mac : /usr/local/lib/node_modules/eslint. No extra setup or documentation required. I am pretty sure that everyone that use eslint has node.js in their machines, if not - it very easy to install on every platform. This tool will take your TSLint configuration and create the "closest" ESLint configuration from it. At this point in time, it doesn't seem to get stuck anymore (latest vscode, eslint or just the act of upgrading did it?). In this case, we use Husky to run ESLint. I tried adding/removing options from the settings.json: Tried enabling/disabling each of those but nothing changes the behaviour. Look no further. Suppress linting TypeScript code with ESLint. In my case it was something about an async Webpack config and getPackageMetaSync from package-meta looping endlessly. This issue has been closed automatically because it needs more information and has not had recent activity. I've checked the other project where this happened for me. The eslint node module will be installed on the global node modules directory. @cchaos @myasonik I'd be curious if it happens to you after the latest VSCode upgrade still. Conclusion Setup takes hours and days. @myasonik thanks for your willingness to debug this. Automatically Fix Code in VS Code. I have nodejs v7.9.0 and npm v4.4.4 on my Windows 8 machine. @cchaos which file are you usually editing when you see this. Interestingly the linter hangs on a configuration file of the repository which tries to sync get a port. The repo that some of us have been having trouble with this in is https://github.com/elastic/eui. See also our issue reporting guidelines. This could be off by default so users not running into those problems will never be affected by it, but for us in this thread knowing we might run into it we could use it to automatically have eslint reload? As I'm the only one of my team experiencing that, I have to spot a difference somewhere and I'll tell you if I find something. In that case you have to be more specific and include --ignore-pattern flag to ignore unwanted file types. I know that other people working on that repository are having the same issue, so I hope with that above repo it should be easily reproducible. 2. If that command is not highlighted, use the keyboard or mouse to select it. I spent way too much time this weekend debugging Vue.js - Vetur - Prettyhtml - Prettier - Beautify - Eslint issues. I am not sure what the ESLint extension can do about this except offering a command to reload ESLint. Can you try a few other options? ... 'eslint --init' in the workspace folder Workspace Alternatively you can disable ESLint by executing the 'Disable ESLint' command. Notice in the screenshot below how ESLint warnings in VSCode editor include style errors from Prettier. May that helps to track this down. Making eslint ignore the file, and then doing 'Clear Editor History' made the issue go away. You probably run npm run lint — –fix but that will touch tons of the files with linebreaks changed from LF to CRLF – probably not something you want.. How to Fix the eslint linbreak style errors? when this happens do you experience high CPU load ? @dbaeumer You were right my problem was unrelated to this issue. I have written about the importance of static code analysis tools in several places. I have tried to use --resolve-plugins-relative-to with several options but either the parser cannot be found or the plugins cannot be found (my assumption is that if the parser is not found, looking for modules never happens). But with ng new command it will create karma.conf.js and protractor.conf.js that are not compatible with somes eslint rules like no-empty-function or no-var-require. This is accessible globally at Extensions > Extension Library… > ESLint > Preferences, and per-workspace at Project > Project Settings… > ESLint. https://gist.github.com/timroes/9f15a78f5fc1ed1e1b3cecb94f9195d5, https://github.com/microsoft/vscode-eslint.git, https://github.com/Goldziher/dtsgenerator, Intel(R) Core(TM) i5-7267U CPU @ 3.10GHz (4 x 3100), -psn_0_421991 --crash-reporter-id d4eda43b-3842-4492-8d6b-78ceef6890ab. in the new VS Code instance that opens open the workspace you can trigger the behavior in. If your editor is not represented above, there may be an integration already or a way to use the eslint command directly to achieve a similar effect. Support for eslint is not directly included in the editor. Deprecated: Use --cache-location instead.--cache-location. In many ways, it is similar to JSLint and JSHint with a few exceptions: ESLint uses Espree for JavaScript parsing. Thanks for your time. However already the eslint command in the terminal exposes that: So there is nothing I can do in the ESLint extension to speed this up. # Base Rules (Enabling Correct ESLint Parsing) The 2020-10-06T15:02:34.292Z eslint:linter Verify should at some point be closed with something like eslint:cli-engine Linting complete in: @timroes I tried to reproduce this using the repository you pointed out. just edited the combo_box.tsx file in a couple of places and saved it a couple of times and it got stuck. Here I am ignoring the spec.js files that have their own sets of rules. This is what was causing eslint to be super slow. for example: C:\Users\USER\AppData\Roaming\npm\eslint -c C:\PROJECTPATH\client\.eslintrc C:\PROJECTPATH\client\app\**\*.js --ignore-pattern *.spec.js –fix. @NicolasBuecher I think your problem is unrelated to the slowness described in these issues since ESLint is not working in your setup in the first place. For a good developer experience, it's useful to setup your editor to automatically run ESLint's automatic fix command (i.e. Hello guys, I'm running into this issue for 3 days now, in a private repo (sorry) using Typescript. I suspect that the issue happens if a code base uses the typescript compiler directly - this is what is happening in the above repo. If your editor is not represented above, there may be an integration already or a way to use the eslint command directly to achieve a similar effect. By setting target to either es5 or es6, TypeScript will automatically import a set of libraries (i.e. Your Visual Studio Code suddenly does not show you the lint errors as well. I e.g. Successfully merging a pull request may close this issue. If none specified .eslintcache will be used. I can see in my settings.json file that I was using the depreciated eslint.validate: [typescript, typescriptreact] and I don't remember having trouble last time I used the repo. There's a lot of other stuff we should be concerned about as well, but formatting is one of those things that we can set up right off the bat and establish a standard for our project. However, whenever you are unsure about the ESLint warning, search it in your favorite search engine and evaluate whether you want to have this ESLint rule or not. I am wondering if there might be different plugins which can be stuck in that way and if vscode-eslint could be "more smart" about detecting those hangs independent on what crashed freezes eslint somehow? Can really no one share a repository with me we I can reproduce this? Coworkers and automation tools (such as a CI) will install ESLint just like they install the other development dependencies of the project. @h3xsoul thanks. In this case, we use Husky to run ESLint. I am so far always using the "Developer: Reload Window", but only reloading eslint would be nicer. node_modules/eslint/bin/eslint.js ./src/core/Scene/Scene.ts, 77:5 error Unexpected console statement no-console, 78:1 error Expected indentation of 4 spaces but found 6 @typescript-eslint/indent, 78:7 error Unexpected console statement no-console, 78:23 error Trailing spaces not allowed no-trailing-spaces, 79:1 error Trailing spaces not allowed no-trailing-spaces. 3、检验是否安装成功eslint -v 出现错误提示:command not found:eslint 出现类似command not found的错误,要么是没有真的完成相关包的安装、要么是没有刷新配置,或者是软链接目录配置错误,一般根据这些思路进行排除错误。 2.
