title: Anaconda won't update spyder
body: <p>I had Spyder 3.1.3 installed an running fine. 
  Then I heard about "anaconda navigator" - which I never had launched it before - so I launched it, took a look around, installed glueviz and quit. </p>
  
  <p>Next time I opened spyder - not from the navigator, from the shortcut I've always used (with this command: <code>C:\Anaconda2\pythonw.exe C:\Anaconda2\cwp.py C:\Anaconda2 "C:/Anaconda2/pythonw.exe" "C:/Anaconda2/Scripts/spyder-script.py" --new-instance</code>), it launched spyder version 2.3.8.</p>
  
  <p>Then I went to the command line and tried to update spyder with the <code>conda update spyder</code>command and I get this:</p>
  
  <pre><code>C:\&gt;conda update spyder
  Fetching package metadata ...........
  Solving package specifications: .
  
  # All requested packages already installed.
  # packages in environment at C:\Anaconda2:
  #
  spyder                    2.3.8                    py27_1
  
  C:\&gt;
  </code></pre>
  
  <p>nothing happens.
  If I try to update it from the navigator (running as admin), I get an error saying  "spyder cannot be installed on this environment"</p>
  
  <p>Any ideas what can I do to properly update spyder?</p>
  
  <p>EDIT:
  I updated pandas and skpyder downgraded to version 2.2.0...</p>
  
  <p>Thanks</p>
