Cython with pythonxy

I'm trying to use Cython but I can't seem to find a way of getting it to work.

  1. I installed pythonxy, which comes with Cython.
  2. I installed MS VS 2008 Express (https://go.microsoft.com/?linkid=7729279)
  3. Then I installed the Cython plugin for pythonxy from the standard plugins web page (https://code.google.com/p/pythonxy/wiki/StandardPlugins) just in case.

However, I get this error:

ImportError: Building module MyCyModule failed: ["ValueError: [u'path']\n"]

I have my MWE below:

MyCyModule.pyx

print 'Hello World'

TestCyModule.py

import pyximport
pyximport.install()
import MyCyModule
Solution

  • To solve this I installed: Windows SDK for Windows Server 2008 and .NET Framework 3.5
