I have tried uninstalling global packages in several ways.

npm uninstall -g <package_name> this didn't work.

I managed to remove the global packages in the following way:

Goto terminal
Run this command npm list -g
Goto the path (C:UsersuserAppDataRoaming
pm)
Delete all the related files to your package
Goto node_modules find and delete the package
This should work.

npm delete

npm ls -gp --depth=0 | awk -F/ '/node_modules/ && !//npm$/ {print $NF}' | xargs npm -g rm
