ESLint couldn't find the config "airbnb-base" to extend from

Question

in folder1, i did "npm install", run "eslint --ext.js.", all good.

Then i copied all the subfolder/files from folder1 to folder2, including.eslintrc, .jest, .npmrc, package.json, package-lock.json. After npm install, i got this

> eslint --ext .js .


Oops! Something went wrong! :(

ESLint: 7.32.0

ESLint couldn't find the config "airbnb-base" to extend from. Please check that the name of the config is correct.

How can this happen? how to fix this pls? The eslint in folder1 has the same version.

Answer 1

ok, for folder2, the package.json did miss eslint-config-airbnb-base. Added it and worked. Not sure why folder1 worked, maybe got from its parent folder.

Answer 2

You can delete ' .eslintrc ' in the father of the folder2!
