Particle-cli not working?

Troubleshooting
1

Trying “particle serial monitor” getting this:

Please reinstall the CLI again using npm install -g particle-cli
Cannot read property 'list' of undefined
Caught Interrupt.  Cleaning up.

Then trying that I get this:

Ok, I had done sudo install for the particle-cli. Deleted libraries, reinstalled, works now.

Just adding my 2¢ here:

sudo npm uninstall -g --unsafe-perm particle-cli
sudo npm install -g --unsafe-perm particle-cli

This always fixes this issue for me.
