Using npm, I'm having trouble installing angularjs version 1.5.7. My package has been prepared. The following is a json file.
{
 "name": "angular",
 "version": "1.5.7"
}
When I run the following command in the terminal where my project is:
sudo npm install angular@1.5.7 --save
The following error notice appears:
npm ERR! Linux 4.4.0-24-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "install" "angular@1.5.7" "--save"
npm ERR! node v6.2.2
npm ERR! npm  v3.9.5
npm ERR! code ENOSELF
npm ERR! Refusing to install angular as a dependency of itself

This is my first time using npm to install angularjs, so I'm not sure what I'm doing wrong.
