npm WARN eslint-plugin-vue@6.2.2 requires a peer of eslint@^5.0.0 || ^6.0.0 but none is installed

Why do I get this error message while I already have a version of eslint higher than 5.0.0 in my Laravel project ?

$ npm install
npm WARN eslint-plugin-vue@6.2.2 requires a peer of eslint@^5.0.0 || ^6.0.0 but none is installed. You must install peer dependencies yourself.

$ eslint -v
v7.9.0
Solution

  • Read what the caret "^" does in semantic version syntax. Generally speaking, the caret means: ^version “Compatible with version”, will update you to all future minor/patch versions, without incrementing the major version. ^2.3.4 will use releases from 2.3.4 to <3.0.0.

    Since you have version 7.9.0, that is neither compatible with 6 nor with 5, so it's normal that it gives you an error.
