在Mac 10.10上M2Crypto导入失败

Question

我已经尝试了所有可能的方法在Mac上安装M2Crypto。

下面的链接首先是构建openssl，然后是swig，然后是M2Crypto：http://jonatkinson.co.uk/2008/10/09/installing-m2crypto-osx/

以下链接用于更改M2Crypto的setup.py，以创建libssl.a和libcrypto.a的静态链接，但这也不起作用：https://github.com/accessgrid/accessgrid/blame/master/packaging/mac/setup.py.m2crypto-0.17.patch

import M2Crypto

在尝试安装saltstack时遇到了完全相同的问题。使用easy_install修复。

easy_install M2Crypto-0.21.1-py2.7-macosx-10.8-intel.egg

从M2Crypto下载的M2Crypto-0.21.1-py2.7-macosx-10.8-intel.egg文件

还有这篇文章：http://jonatkinson.co.uk/2008/10/09/installing-m2crypto-osx/可能会有所帮助
