无法在Windows 8.1 64位计算机中安装M2Crypto包

Question

我使用的是安装了python2.7的Win8.1 64位机器。我已经安装了swigwin 3.0.5。当m2i安装密码时出现以下错误：

SWIG\_m2crypto.i(30) : Error: Unable to find 'openssl\opensslv.h'

SWIG\_m2crypto.i(33) : Error: Unable to find 'openssl\safestack.h'

SWIG\_evp.i(12) : Error: Unable to find 'openssl\opensslconf.h'

SWIG\_ec.i(7) : Error: Unable to find 'openssl\o,pensslconf.h'

在一些链接中，我发现建议安装openssl-dev，但我找不到与windows相同的软件包（pip install openssl dev不起作用，我已经完成了pip install pyOpenSSL，这对我没有帮助）。在

提前谢谢。在

Answer 1

我通过以下方法解决了这个问题（在Windows上的MiniConda安装中）：

1. conda安装openssl
2. 将<；MiniConda directory>；\envs\<；environment>；\Library\include\openssl复制到<；MiniConda directory>；\envs\<；environment>；\include\openssl（或mklink it）

它可能也适用于其他Python环境。在

但是，我遇到了更多的问题（我不知道如何解决）：

在Windows上安装M2Crypto是一件痛苦的事。幸运的是，有些人已经开始为M2Crypto创建Windows安装程序：

• https://pypi.python.org/pypi/M2CryptoWin64
• http://the.randomengineer.com/2014/07/29/ssl-for-python-m2crypto-on-windows/

您也可以直接从M2Crypto制造商那里使用稍旧版本的软件包，因为他们实际上提供了一段时间的Windows可安装版本：
