'eslint' is not recognized as an internal or external command

I'm trying to install eslint & run it in vs code. I ran this command:

npm i -g eslint

and it seemed to work, but I keep getting an error when I try to run eslint :

"'eslint' is not recognized as an internal or external command, operable program or batch file".

What gives?

It was the same error for me

I resolved this issue by using the below command :

npm -g i eslint-cli
npm i eslint-plugin-promise@latest --save-dev

Well, if you are a Windows user and installing eslint-cli is not working for you, try :

node node_modules\eslint\bin\eslint.js --help

Or, you can use npx which lets you run local commands in node_modules/.bin :

npx eslint --help

For yarn use :

yarn eslint --help

Note:

This answer is updated to include yarn and npx.
This issue is related to modules installed locally.

Solution posted works for me: Step 1: eslint install globally npm -g i eslint-cli

Step 2: eslint install locally npm i eslint --save-dev

adding 2 more step: Step 3: eslint --init

It ask various questions e.g. √ How would you like to use ESLint? · style √ What type of modules does your project use? · none √ Which framework does your project use? · none √ Does your project use TypeScript? · No / Yes √ Where does your code run? · browser √ How would you like to define a style for your project? · prompt √ What format do you want your config file to be in? · JavaScript √ What style of indentation do you use? · tab √ What quotes do you use for strings? · single √ What line endings do you use? · unix √ Do you require semicolons? · No / Yes

Answer them based on your need.

Step 4: eslint yourfile.js This will show errors/warnings with your file. This way linting process is completed for js file.
