Fixed.

Error: Cannot find module 'semver'
Require stack:
- ...\firebase\tools\lib\node_modules\firebase-tools\lib\bin\firebase.js

Delete the folder referenced (above) and re-run firebase (below)

> firebase login

It will take a while to rebuild the directory, but let it go and it will work.

I am having a similar issue whenever I run firebase commands. you say “delete the folder referenced (above)” but you mention a file. What folder needs to be deleted?
