I'm having this issue after clearing the cache by running npm cache clean --force and removing the %appdata%/npm-cache directory.

Same issue here, even after a cache clear. Using angular v9.

I have the same problem, cache cleared, folder removed etc.

I will check that once again

I was just pulling my hair out over the same issue. Issue is ng add installs an out of date version (I forget which one, but something ancient). Clearing caches, deleting node_modules/, and reinstalling made no difference.

Workaround: just specify the version you want (eg. ng add ngx-auth-firebaseui@latest)
