Python M2Crypto DLL 加载失败，找不到指定的模块

Question

我正在尝试将此切片用于我的 web2py 应用程序 http://www.web2pyslices.com/slices/take_slice/106

我安装了模块 M2Crypto 并跟随切片，当加载页面时我收到此错误

Traceback (most recent call last):
  File "F:\Projects\Web2py\w1992\gluon\restricted.py", line 194, in restricted
    exec ccode in environment

    level)
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

所以我尝试直接从 Python 导入模块我打开终端并输入

>>> import M2Crypto
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.
>>>

无论如何要解决这个问题？？

有同样的问题，通过从这里安装 OpenSSL for Windows 修复它:http://slproweb.com/products/Win32OpenSSL.html

我将 OpenSSL 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)一起使用没问题。
