Getting error: unknown file type '.pyx' when installing from source

I'm trying to build on a cluster where I'm having to manually install everything from source. When I run:
python setup.py install --prefix=...
I get the error:

building 'triangle.core' extension
error: unknown file type '.pyx' (from 'triangle/core.pyx')

I'm using:

  • python version 2.7.2
  • numpy version 1.6.2
  • setuptools version 18.4
  • cython version 0.24.1

Using the first answer here I modified setup.py with the attached patch and it worked. I'm not familiar with python setup so can't comment on why this is necessary on this cluster (but isn't necessary on my local machine) but wanted to flag it in case it's useful to anyone else.

Try upgrading setuptools. I am using version 23.1.0

Hello @cianwilson. I've had such problem. Issue #12 is all about problems with installation. You sould use this advice. from @sinback (thank you, @sinback, again and again). It helped me, I think it will help you.
