Error on npm install: "no space left on device"

Whenever I try to add the “request” lib in package.json, I get the following error:

Okay problem is solved now. But I don’t know why. It was just working after some time.

Yeah, it will have been full and then resolved. Sorry for the interruption, but I’m glad it’s sorted now.
