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

}
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
