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

Question

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

Because that doesn't say "higher than 5.0.0", it says "5.x.y or 6.x.y". Have you actually had a problem running the linting? — jonrsharpe, Sep 25 '20 at 10:23

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.
