[Solved] ESLint not working in VS Code?

ESLint is not working for me in VS Code. I have the plugin installed in VS Code, and ESLint itself as a developer dependency in my package.json, which I have installed as well.

I modified the following option in the VS Code User Settings:

  "eslint.options": { "configFile": "C:/mypath" }

I have use the command eslint --init to add the basic .eslintrc.json to the main directory of my package.

Other people were able to get ESLint feedback from VS Code using the exact same package with the exact same ESLint config file.

I have received no feedback of any kind when directly breaking multiple rules that were all included in the recommended rule set that is by default inside of the .eslintrc.json file.

What am I missing?

Edit: I have tested using ESLint via command line, and everything worked as expected, with the errors found where they should have, however, these same errors never showed up in VS Code. The issue seems to be on VS Code’s side and not ESLint.

Solution #1:

There are a few reasons that ESLint may not be giving you feedback. ESLint is going to look for your configuration file first in your project and if it can’t find a .eslintrc.json there it will look for a global configuration. Personally, I only install ESLint in each project and create a configuration based off of each project.

The second reason why you aren’t getting feedback is that to get the feedback you have to define your linting rules in the .eslintrc.json. If there are no rules there, or you have no plugins installed then you have to define them.

Solution #2:

If ESLint is running in the terminal but not inside VSCode, it is probably
because the extension is unable to detect both the local and the global
node_modules folders.

To verify, press Ctrl+Shift+U in VSCode to open
the Output panel after opening a JavaScript file with a known eslint issue.
If it shows Failed to load the ESLint library for the document {documentName}.js -or- if the Problems tab shows an error or a warning that
refers to eslint, then VSCode is having a problem trying to detect the path.

If yes, then set it manually by configuring the eslint.nodePath in the VSCode
settings (settings.json). Give it the full path (for example, like
"eslint.nodePath": "C:Program Filesnodejs",) — using environment variables
is currently not supported.
This option has been documented at the ESLint extension page.

Solution #3:

In my case, since I was using TypeScript with React, the fix was simply to tell ESLint to also validate these files. This needs to go in your user settings:

"eslint.validate": [ "javascript", "javascriptreact", "html", "typescriptreact" ],

Solution #4:

configuring working directories solved it for me, since I had multiple projects with own .eslintrc files openend in the same window.

Put this in your .vscode/settings.json

"eslint.workingDirectories": [

thanks to this guy on github:

PS: useful command to list all subdirectories containing an .eslintrc except /node_modules:

find . .eslintrc | grep .eslintrc | grep -v node_modules

Solution #5:

Case 1/2: First-time plugin installation? approval is necessary

Little “weird” user experience (Hard to notice) – anyway – Since V 2.1.10 –
You must change the “currently block” status bar enter image description here on New/First installation.

ESLint plugin Version 2.1.10 changelog (08/10/2020)

no modal dialog is shown when the ESLint extension tries to load an
ESLint library for the first time and an approval is necessary.
Instead the ESLint status bar item changes to ESLint status icon
indicating that the execution is currently block.

Click on the status-bar (Right-Bottom corner):
enter image description here

Opens this popup:

enter image description here

Approve ==> Allows Everywhere

enter image description here

-or- by commands:

ctrl + Shift + p — ESLint: Manage Library Execution

enter image description here

Read more here under “Release Notes”:

Case 2/2: The plugin already installed/approve

Open the terminal Ctrl+`

Under output ESLint dropdown, you find useful debugging data (Errors, warnings, info).

enter image description here

For example, missing .eslintrc-.json throw this error:
enter image description here

Error: ENOENT: no such file or directory, realpath

Next, check if the plugin enabled:
enter image description here

Last, Since v 2.0.4 – eslint.validate in “normal cases” (react, vue, typescript, js, html, md) not necessary anymore (old legacy setting)

**Many out-of-date stackoverflow answers indicate that eslint.probe file should be edited.

eslint.probe = an array for language identifiers for which the
ESLint extension should be activated and should try to validate the
file. If validation fails for probed languages the extension says
silent. Defaults to [javascript, javascriptreact, typescript,
typescriptreact, html, vue, markdown].

In my case, I had not installed he ESLint extension in VSCode, which was causing issue. Did it and it started working again.

Respondent: Ezra Siton

Solution #7:

Since you are able to successfully lint via command line, the issue is most likely in the configuration of the ESLint plugin.

Assuming the extension is properly installed, check out all ESLint related config properties in both project (workspace) and user (global) defined settings.json.

There are a few things that could be misconfigured in your particular case; for me it was JavaScript disabled after working with TypeScript in another project and my global settings.json ended up looking following:

"eslint.validate": [
  { "language": "typescript", "autoFix": true }

From here it was a simple fix:

"eslint.validate": [
  { "language": "javascript", "autoFix": true },
  { "language": "typescript", "autoFix": true }

This is so common that someone wrote a straight forward blog post about ESLint not working in VS Code. I’d just add, check your global user settings.json before overriding the local workspace config.

Solution #8:

Restarting VSCode worked for me.

Solution #9:

In my case ESLint was disabled in my workspace. I had to enable it in vscode extensions settings.

Respondent: thedanotto

Solution #10:

If you are using a global installation of ESLint, any plugins used in your configuration must also be installed globally. Like wise for local install.
if u have installed locally and properly configured locally, yet eslint isn’t working, try restarting your IDE.
This just happened to me with VScode.

Solution #11:

I use Use Prettier Formatter and ESLint VS Code extension together for code linting and formating.

enter image description here

enter image description here

now install some packages using given command, if more packages required they will show with installation command as an error in the terminal for you, please install them also.

npm i eslint prettier [email protected]^5.16.0 eslint-config-prettier eslint-plugin-prettier eslint-config-airbnb eslint-plugin-node eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react [email protected]^2.5.0 --save-dev

now create a new file name .prettierrc in your project home directory, using this file you can configure settings of the prettier extension, my settings are below:

  "singleQuote": true

now as for the ESlint you can configure it according to your requirement, I am advising you to go Eslint website see the rules (

Now create a file name .eslintrc.json in your project home directory, using that file you can configure eslint, my configurations are below:

  "extends": ["airbnb", "prettier", "plugin:node/recommended"],
  "plugins": ["prettier"],
  "rules": {
    "prettier/prettier": "error",
    "spaced-comment": "off",
    "no-console": "warn",
    "consistent-return": "off",
    "func-names": "off",
    "object-shorthand": "off",
    "no-process-exit": "off",
    "no-param-reassign": "off",
    "no-return-await": "off",
    "no-underscore-dangle": "off",
    "class-methods-use-this": "off",
    "prefer-destructuring": ["error", { "object": true, "array": false }],
    "no-unused-vars": ["error", { "argsIgnorePattern": "req|res|next|val" }]

Solution #12:

I had similar problem on windows, however sometimes eslint worked (in vscode) sometimes not. Later I realized that it works fine after a while. It was related to this issue: eslint server takes ~3-5 minutes until available

Setting enviroment variable NO_UPDATE_NOTIFIER=1 solved the problem

Solution #13:

I’m giving the response assuming that you have already defined rules in you local project root with .eslintrc and .eslintignore.
After Installing VSCode Eslint Extension several configurations which need to do in settings.json for vscode

eslint.enable: true
eslint.nodePath: <directory where your extensions available>

Installing eslint local as a project dependency is the last ingredient for this to work. consider not to install eslint as global which could conflict with your local installed package.

Solution #14:

I had a similar problem with eslint saying it was ‘..not validating any files yet’, but nothing was reported in the VS Code problems console. However after upgrading VS Code to the latest version (1.32.1) and restarting, eslint started working.

Respondent: LasithaMD

Solution #15:

In my case setting eslint validate to :
“eslint.validate”: [ “javascript”, “javascriptreact”, “html”, “typescriptreact” ],
did the job.

Respondent: PRS

Solution #16:

If you are developing a project with eslint as an package.json dependency, make sure you run npm install. That fixed it for me.

Respondent: Tomasz Ostroga

Solution #17:

For me, i did accidentally disable ESLint when some prompt was shown by it.

Doing below steps fixed it for me

  1. Shift + Command + P and select ESLint: Disabled ESLint
  2. Close vscode
  3. Shift + Command + P and select ESLint: Show Output Channel

Solution #18:

In my case, it wasn’t working because I had added only one folder of the monorepo to the project, even though I had the package.json and the extension configured. I worked only when I added the whole project (which contained the package.json file) to the VS Code.

Respondent: Abdul Vajid

Solution #19:

Go to your settings.json file, add the following and, fix the eslint.nodepath. Tailor it to your own preferences.

  "editor.codeActionsOnSaveTimeout": 2000,
  "editor.codeActionsOnSave": {
    "source.fixAll": true
  "editor.fontSize": 16,
  "editor.formatOnSave": true,
  "explorer.confirmDragAndDrop": true,
  "editor.tabSize": 2,
  "eslint.codeAction.showDocumentation": {
    "enable": true
  "eslint.nodePath": "C:{path}",
  "eslint.workingDirectories": ["./backend", "./frontend"],

Solution #20:

In my case, I had the .eslintrc.json file inside the .vscode folder. Once I moved it out to the root folder, ESLint started working correctly.

Respondent: DJN

Solution #21:

You can open problem tab to check there is an ESLint permission request or not. If you see it, try to click the lightbulb and fix the issue, it works for me.

problem tab in vscode terminal window

wish you luck!
