title: Cannot run Spyder because No module named 'PySide'
body: <p>I wanted to try using Spyder IDE. I was reading this page on how to open and run Spyder: <a href="https://github.com/spyder-ide/spyder/releases" rel="noreferrer">https://github.com/spyder-ide/spyder/releases</a></p>
  
  <p>I typed the following commands as specified in the page:</p>
  
  <pre><code>conda update qt pyqt
  conda update spyder
  </code></pre>
  
  <p>Both commands gave "# All requested packages already installed.".</p>
  
  <p>I then typed spyder into my terminal (Mac):</p>
  
  <pre><code>Macs-MacBook:~ macuser$ spyder
  Traceback (most recent call last):
    File "/anaconda3/lib/python3.6/site-packages/qtpy/__init__.py", line 166, in &lt;module&gt;
      from PySide import __version__ as PYSIDE_VERSION  # analysis:ignore
  ModuleNotFoundError: No module named 'PySide'
  
  During handling of the above exception, another exception occurred:
  
  Traceback (most recent call last):
    File "/anaconda3/bin/spyder", line 11, in &lt;module&gt;
      sys.exit(main())
    File "/anaconda3/lib/python3.6/site-packages/spyder/app/start.py", line 159, in main
      from spyder.app import mainwindow
    File "/anaconda3/lib/python3.6/site-packages/spyder/app/mainwindow.py", line 49, in &lt;module&gt;
  </code></pre>
  
  <p>So, I tried to install PySide:</p>
  
  <pre><code>Macs-MacBook:~ macuser$ conda install PySide
  Solving environment: failed
  
  UnsatisfiableError: The following specifications were found to be in conflict:
    - anaconda==5.2.0=py36_3
    - pyside
  Use "conda info &lt;package&gt;" to see the dependencies for each package.
  </code></pre>
  
  <p>What should I do to get up and running with Spyder?</p>
