Actual Behavior

There is an error because of the fixed ESLint version in the react-scripts package.

Question

Why does react-scripts keeps fixed versions of packages such as eslint in the dependency manifest? Why not just specify the major version, like eslint-config-react-app does (5.x, for example)?

https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/package.json#L40

Notice how eslint-config-react-app sets its ESLint version: https://github.com/facebook/create-react-app/blob/master/packages/eslint-config-react-app/package.json#L17
