It may be because the .npm directory was created under the root user. I currently executing user npm install the non-root user. SO, it is OK to change the .npm directory permissions in the root directory to the current user's permissions. Sudo chown -R $USER:$GROUP ~/.npm

If it still doesn't work, then emptying the tmp directory should work fine. Rmdir ~/tmp

Now executing npm install should be able to install project dependencies normally.
