Cannot find module 'eslint-config-react-app'

Is this a bug report?

Yes

Can you also reproduce the problem with npm 4.x?

Didn’t try 4. I’m using lts/carbon with yarn.

Which terms did you search for in User Guide?

I looked through the user guide and found Usage in Create React App Projects which indicates that it should be available as part of Create React App.

Environment

1. node -v: 8.9.3
2. npm -v: 5.5.1
3. yarn --version (if you use Yarn): 1.3.2
4. npm ls react-scripts (if you haven’t ejected): 1.0.17

Then, specify:

1. Operating system: macOS 10.12.6
2. Browser and version (if relevant): Chrome/N/A

Steps to Reproduce

(Write your steps here:)

1. create-react-app eslint-dep
2. cd eslint-dep
3. yarn global add eslint
4. echo '{"extends": "react-app"}' > .eslintrc
5. eslint src

Expected Behavior

I thought I’d have all the necessary eslint plugins to run eslint src with the react-app plugin.

Actual Behavior

Cannot find module 'eslint-config-react-app'
Referenced from: /Users/typeoneerror/Dev/eslint-bug/.eslintrc.json
Error: Cannot find module 'eslint-config-react-app'

This may be simply a dependency issue, but it may be a documentation issue as the eslint-config-react-app package says I should have this already as part of CRA.

For anyone else trying this, one solution is installing eslint-config-react-app globally, along with all of its peer deps. At the moment, that’s:

npm i -g babel-eslint@^7.2.3 eslint@^4.1.1 eslint-plugin-flowtype@^2.34.1 eslint-plugin-import@^2.6.0 eslint-plugin-jsx-a11y@^5.1.1 eslint-plugin-react@^7.1.0

You have to have the ‘eslint-config-react-app’ package in the same “scope” of your eslint installation. If you installed eslint globally (by using ‘npm install -g eslint’ or ‘yarn global add eslint’) you should do the same for “eslint-config-react-app”… if you installed locally (npm without -g or yarn without global), you should install the config package in the same way.
