Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "C:\Python27\lib\site-packages\M2Crypto\__init__.py", line 23, in <module 
> 
    import m2 
    File "C:\Python27\lib\site-packages\M2Crypto\m2.py", line 28, in <module> 
    from __m2crypto import * 
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

有同样的问题，从这里安装OpenSSL时为Windows固定它：http://slproweb.com/products/Win32OpenSSL.html

我使用OpenSSL的v1.0.1b（安装到系统目录的DLL）与M2Crypto 0.21.1和Python 2.7.3（所有32个版本）没问题。
