how to deal with ERESOLVE unable to resolve dependency tree

You have dependency conflict (incorrect & potentially broken dependency)
Try to run the command with --force, or --legacy-peer-deps.
If it doesn't take effect, the temporary solution is using prior 
versions of the Node.js (downgrading the Node.js version) as
it causes this kind of errors to happen sometimes.
