title: No supported color terminal library Python/Jupyter
body: <p>I'm trying to start a Jupyter Notebook server on my Windows 7 machine, but I keep getting this odd, seemingly unsearchable error after typing:</p>
  
  <pre><code>jupyter notebook
  </code></pre>
  
  <p>into cmd.exe</p>
  
  <pre><code>C:\Users\zfleeman&gt;jupyter notebook

  <p>This looks like more of a Windows problem than a Python problem. Can somebody give me some advice? I just need to launch my Notebook server.</p>
