无法安装pyOpenSSL

Question

我在Macbook Pro上双重启动了Windows 10分区: Mac: El Capitan (64位) Windows: Windows 10 64位，使用fat文件系统格式化

在Windows上，我安装了cygwin和Python 2.7。通过cygwin，我安装了pip和gcc。

我也尝试过用http://www.lfd.uci.edu/~gohlke/pythonlibs/#cffi安装cffi，但是当我运行pip install cffi-1.8.2-cp27-cp27m-win_amd64.whl时，我得到了错误：cffi....whl is not supported on this platform。然后我尝试了很多我记不起来的东西，我想我甚至尝试过下载tar文件，然后现在，当我运行pip install cffi时，我被告知它已经安装了。

然后我运行了pip install pyOpenSSL，但是，我得到了这个错误：

我在做pip install cryptography的时候也遇到了这个错误。

我在某个地方读到了我应该尝试一下：pip install --global-option build_ext --global-option --compiler=mingw64 pyopenssl，我得到了：

Skipping bdist_wheel for pyopenssl, due to binaries being disabled for it.

有人能告诉我出什么问题了吗？？

更新:通过cygwin安装mingw64x86_64-openssl: OpenSSL encryption library for Win64 toolchain并运行pip install pyopenssl后，我得到了：

我遇到了类似的问题，并安装了libssl头文件，这样我就可以编译python模块：

sudo apt-get install libssl-dev
