python–gcc：_mssql.c：没有这样的文件或目录

我正在尝试为python 2.5编译pymssql.我这样做是因为我认为我拥有的pymssql版本是为python 2.4编译的.这是我得到的错误让我认为：

/home/username/lib/python2.5/pymssql.py:30: RuntimeWarning: Python C API version mismatch for module _mssql: This Python has API version 1013, module _mssql has version 1012.
import _mssql


无论如何我在Ubuntu 10.10上并通过deadsnakes ppa安装了python2.5和python2.5-dev.我创建了一个使用python2.5的virtualenv就像这样

mkvirtualenv pymssql -p /usr/bin/python2.5


我从pip安装cython并尝试从pip安装pymssql但是我收到了这个错误

任何想法如何解决这个问题？

解决方法:

结果我需要从pip安装pyrex.

pip install pyrex
