mkdir npm
npm config set prefix=~/npm
In ~/.profile, add at the end:

amber-cli is all you need to develop Amber applications. If you want to modify Amber, you would clone the Amber Github repo.
npm -g install amber-cli
This should give you version 0.13
Note: To save disk space, you can install all three by single npm install bower grunt-cli amber-cli
