Answer 1

Insufficient permission ('permission denied'), sudo npm install -g xxx

Answer 2

It’s not a source issue. It’s because you don’t have permission
You need to find out the permissions of osx/liunx first
Users don’t have permission to write to the system directory (/usr/local/lib/node_modules)
Users can only write~/or/User/你的账户名 Below

If you have to write to the system directory, enter sudo in front of the command to grant super permissions
