Fix The Error “Plugin “react” was conflicted between “package.json » eslint-config-react-app»”. This is a problem because the react-eslint package installs eslint, but if you install it in your project with npm, it will be in conflict with the react package.
The fix for this error is to update React dependencies in package.json to the latest version of React.
The first thing that you need to do is to find out which version of react your project is using. The easiest way to see this is by looking in package.json > dependencies> react and package.json > dependencies> react-dom > version.
Next, you need to update your configs in package.json. See details at
