node.js - Impossible to install bcrypt with npm on EC2 -

At an Amazon EC2 instance on an Ubuntu server 14.04, I had an error while installing npm . It failed to set bcrypt ( "bcrypt": "^ 0.8.1" in my package.json ).

I have an error here:

 I just had to install build tools  sudo apt-get ADT with any problem with the apt-dock To get you to get  apt-get update  
 
 install - otherwise you  e: failed to fetch ...  
 
 Then  Install NPM  again and you can go!
