I've tried creating a simple little package and uploaded it to PyPi. When I try to install it however, pip tries to download and install ctypes (and fails at compiling it..):
(dev) C:\work\dev>pip install --upgrade dosbox-screen
Downloading/unpacking dosbox-screen
Running setup.py egg_info for package dosbox-screen

I'm using Python 2.6.6 in a virtual env, so any ctypes requirement should already be satisfied:
(dev) C:\work\dev>python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> ctypes.__file__
'c:\\python26\\Lib\\ctypes\\__init__.pyc'
The first version of my setup.py file listed it as a requirement, but the current version does not:
setup(
name='dosbox-screen',
version='0.0.3',
requires=['colorama'],
install_requires=['colorama'],
...
what am I doing wrong?
Did you upload the new version? It looks like pip is installing the older version (with the ctypes dep) that you mention. Try passing -v arguments to get more verbose output.
