how to change eslint 4.* to eslint 3.* in react package.json

Question

Getting the 'propTypes' is not defined no-undef

I have found that the issue is because of ESLint version 4.* And we have to change it to ESLint version 3.* .

I have created my react app by using the create-react-app which installs the webpack , ESLint and babel by default .

I am not sure how to install the ESLint version 3.* and remove the current version .

@btmills - It was a typo mate , i used propTypes.object instead of PropTypes.object . — Shyam, Nov 07 '17 at 12:18

I think you need to eject the app to make that change. create-react-app configuration can only be changed after you eject the app.

Yes @lavish i came across that somwhere , but am not sure how to do that . I am just a beginner in react . I could see that the eslint is in the package-lock.json and the version is "4.10.0" – Shyam Nov 04 '17 at 08:39
