title: python, anaconda, Spyder -- uninstalling python package using pip DOES NOT work in Spyder + ipython
body: <p>By using pip, I can successfully install new packages in ipython running in the Spyder environment. All I need to run is this:</p>
  
  <pre><code>!python -m pip install mypackage
  </code></pre>
  
  <p>However, trying to uninstall packages doesn't seem to work, at all. When I run:</p>
  
  <pre><code>!python -m pip uninstall mypackage
  </code></pre>
  
  <p>The console goes into a state of hanging. It's not strictly 'hanging' because neither Spyder nor the console hangs but the command just isn't returning anything</p>
  
  <p>I am attaching a screenshot to help explain what I mean. The screenshot shows what happens AFTER I have pressed ENTER on this line - and nothing happens!</p>
  
  <p>Does anything know why?</p>
