Installing MEAN stack


I’ve been trying to install the MEAN stack on cloud9, but i can’t figure out a way. The method requires that i have root access…

And on , it just gets stuck ----

Cloning the MEAN repo.......

Running npm install for you....
This may take a couple minutes.
Error: Command failed: cd mean && npm install
