A common error when we update NPM version’s or when we download a project that has been compiled with a previous version, is that when we try to install the dependencies we get “unable to resolve dependency tree”.
This is probably a dependency conflict (incorrect and potentially broken dependency) , so to resolve it, a fast track can be simply try running the command with –force, or –legacy-peer-deps
npm install --legacy-peer-deps
Before executing previous command, we could try to delete node_modules and package-lock.json and then run “
npm install” Or Cleaning the npm cache. “
npm cache clean --force” and running “
npm install --force“
