Answer 1

Its a permission issue

i would recommned you configure npm to not require sudo/Admin permission to install global packages.

for now just downgrade your npm version or run your cmd with 'Admin privileges'.

if these steps doesn't help

then run this npm cache clean --force and then try reinstalling your package.
