Installing Karma behind proxy


As part of working with AngularJS, I tried to install Karma test runner by using npm on one of our new Build Slaves. I got this error while executing the installation.
$ npm install karma

npm http 200 http://registry.npmjs.org/abbrev
> phantomjs@1.9.7-6 install /usr/lib/node_modules/karma-phantomjs-launcher/node_modules/phantomjs
> node install.js

}
Make sure your network and proxy settings are correct.
npm ERR! phantomjs@1.9.7-6 install: `node install.js`
npm ERR! Exit status 1

Solution: Turns out that I need to set the proxy for npm:
$ npm config set proxy "http://company-proxy.com:8080"

Then I hit another problem, where the output has this error return code 407: Unauthorized; which means we need to add credential into the proxy config:
$ npm config set proxy "http://username:password@company-proxy.com:8080"
That's it. Installation is successful!

Side notes:

Sometimes, you might need to set the registry and set https-proxy:
npm config set registry http://registry.npmjs.org/
npm config set https-proxy https://username:password@proxy.company.com:8080
