body: <pre><code>WARN [config]: config.configure() is deprecated, please use config.set() instead.
  WARN [plugin]: Cannot find plugin "karma-phantomjs".
    Did you forget to install it ?
    npm install karma-phantomjs --save-dev
  INFO [karma]: Karma v0.10.2 server started at http://localhost:9018/
  WARN [launcher]: Can not load "PhantomJS", it is not registered!
    Perhaps you are missing some plugin?
  </code></pre>
  
  <p>Getting this error. When running npm install karma-phantomjs --save-dev I get an error.</p>
  
  <pre><code>npm ERR! 404 'karma-phantomjs' is not in the npm registry.
  </code></pre>
  
  <p>I installed karma-phantomjs-launcher --save-dev   but i still get an error when running grunt watch.</p>
  
  <p>Anyone else run into this issue?</p>
