title: Cannot install karma-jasmine and phantomjs on Windows 8.1 - what can I do to get it to work?
body: <p>My Question is a little bit different from 
  <a href="https://stackoverflow.com/questions/34379469/cannot-install-jasmine-core-on-windows-7-osx">Cannot install jasmine-core on Windows 7 / OSX</a></p>
  
  <p>I tried this command:</p>
  
  <pre><code>npm install karma karma-jasmine karma-phantomjs-launcher --save-dev
  </code></pre>
  
  <p>I saw in the answer that Karma is not supporting v.5.3.0 of Node (it seems to be the same with my version v.5.2.0 ).</p>
  
  <p>But what can i do? The quoted thread is not giving any answer to solve the problem... Downgrade node and every package I have installed?? How to? Is this working? I am new to these technologies.</p>
  
  <p>Here are the errors I got:</p>
  
  <pre><code>└── UNMET PEER DEPENDENCY jasmine-core@*
  └── UNMET PEER DEPENDENCY phantomjs@&gt;=1.9
  
  npm WARN karma-jasmine@0.3.6 requires a peer of jasmine-core@* but none was installed.
  npm WARN karma-phantomjs-launcher@0.2.2 requires a peer of phantomjs@&gt;=1.9 but none was installed.
  </code></pre>
  
  <p>Another problem is </p>
  
  <pre><code>npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
  npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.6
  </code></pre>
  
  <p>So what can I do?</p>
