Answer 1

I had permissions issues with some of the directories under /usr/local/lib/node_modules. I must have installed some packages with sudo but most under my own user id. I solved this issue on a Mac with these commands:

sudo chown -R `whoami` /usr/local/lib/node_modules/
sudo chgrp -R admin /usr/local/lib/node_modules/
