I had this error once while trying to install the npm package react-devtools.

leiluspocus$ npm i -g react-devtools

The issue was that I was previously installing npm packages using the root user.

I had the weirdest issue when initializing my compass project for Greenie.

I solved it by using a more recent version of Ruby using RVM. RVM is pretty cool because you can switch your Ruby versions very easily. Note that I had to re-install compass afterwards.
