This indicates that you do not have permission to write to the directories that npm uses to store global packages and commands.
How bad is it?

You can fix this problem using one of three options:
- Change the permission to npm’s default directory.
- Change npm’s default directory to another directory.
- Install node with a package manager that takes care of this for you.
