Fix the upstream dependency conflict installing NPM packages

Question

Trying to npm install vue-mapbox mapbox-gl and I'm getting a dependency tree error.

I'm running Nuxt SSR with Vuetify, and haven't installed anything related to Mapbox prior to running this install and getting this error.

38 error code ERESOLVE 39 error ERESOLVE unable to resolve dependency tree 40 error 41 error While resolving: [1mexample[22m@[1m1.0.0[22m 41 error Found: [1mmapbox-gl[22m@[1m1.13.0[22m[2m[22m 41 error [2mnode_modules/mapbox-gl[22m 41 error   [1mmapbox-gl[22m@"[1m^1.13.0[22m" from the root project 41 error 41 error Could not resolve dependency: 41 error [35mpeer[39m [1mmapbox-gl[22m@"[1m^0.53.0[22m" from [1mvue-mapbox[22m@[1m0.4.1[22m[2m[22m 41 error [2mnode_modules/vue-mapbox[22m 41 error   [1mvue-mapbox[22m@"[1m*[22m" from the root project 41 error 41 error Fix the upstream dependency conflict, or retry 41 error this command with --force, or --legacy-peer-deps 41 error to accept an incorrect (and potentially broken) dependency resolution. 41 error 41 error See /Users/user/.npm/eresolve-report.txt for a full report. 42 verbose exit 1 

What's the right way to go about fixing this upstream dependency conflict?

Answer 1

Looks like it's a problem with Peer Dependencies in the latest version of npm (v7) which is still a beta version. try with npm install --legacy-peer-deps for detail info check this https://blog.npmjs.org/post/626173315965468672/npm-v7-series-beta-release-and-semver-major

Answer 2

Use --legacy-peer-deps after npm install. For example, if you want to install radium, use:

npm install --legacy-peer-deps --save radium
