How to Resolve Dependency Conflicts When Installing vue-mapbox and mapbox-gl in Nuxt.js SSR?

Resolving Dependency Conflict During NPM Package Installation

Encountering a dependency tree error while attempting to install packages can be frustrating. Let's examine a specific issue involving the installation of vue-mapbox and mapbox-gl.

Problem Statement:

When executing npm install vue-mapbox mapbox-gl, Nuxt.js SSR users may encounter the following error:

error ERESOLVE unable to resolve dependency tree
...
error peer mapbox-gl@'^0.53.0' from vue-mapbox@'0.4.1'
error Could not resolve dependency:
...

Solution:

This conflict stems from peer dependency issues in npm v7, a beta release. The latest versions of npm resolve peer dependencies differently than previous versions. To resolve this issue, execute:

npm install --legacy-peer-deps

Explanation:

Peer dependencies ensure that packages work together and are compatible versions. In npm v7, peer dependencies are not automatically installed. By using --legacy-peer-deps, you override this behavior and allow npm to install the peer dependencies.
