title: How can I use a Python module in Pydev in Aptana on Windows 7?
body: <p>I'm fairly new to Pydev in Aptana Studio 3, but thanks to some great tutorial videos I've got Python 3.3 running in Pydev just fine on Windows 7.</p>
  
  <p>My reason for using Aptana/Pydev is for all the linty code-tidying goodness, but the bit of code I've been given which I need to refactor uses the <a href="https://pypi.python.org/pypi/RPi.GPIO" rel="nofollow">Rpi.GPIO</a> module.</p>
  
  <p>Works just find when I apt-get the module on the Pi, of course, but I need to do some massive tidying on Windows, then I can go back to IDLE3 on the Pi later.</p>
  
  <p>It looks like you can't just dump the folder in a Pydev path and expect it to run, so I read the INSTALL readme, and the following thing happened:</p>
  
  <pre><code>D:\RPi.GPIO&gt;python setup.py install
  running install
  running bdist_egg
  running egg_info
  writing dependency_links to RPi.GPIO.egg-info\dependency_links.txt
  writing RPi.GPIO.egg-info\PKG-INFO
  writing top-level names to RPi.GPIO.egg-info\top_level.txt
  reading manifest file 'RPi.GPIO.egg-info\SOURCES.txt'
  reading manifest template 'MANIFEST.in'
  writing manifest file 'RPi.GPIO.egg-info\SOURCES.txt'
  installing library code to build\bdist.win-amd64\egg
  running install_lib
  running build_py
  running build_ext
  building 'RPi.GPIO' extension
  error: Unable to find vcvarsall.bat
  </code></pre>
  
  <p>So if anyone knows how to simply get Pydev to recognise this library, I'd be very grateful.</p>
