无法安装pyOpenSSL

Question

我双启动在MacBook Pro上一个Windows 10分区： 的Mac：埃尔卡皮坦（64位） 视窗：视窗10 64位，与FAT文件系统

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

我也尝试安装cffi与http://www.lfd.uci.edu/~gohlke/pythonlibs/#cffi，但是当我运行pip安装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不记得的东西，我想我甚至尝试下载一个tar文件，然后现在，当我运行pip install cffi时，我被告知它已经安装。

我然后跑pip install pyOpenSSL，但是，我得到这个错误：

    compilation terminated.

当我做pip install cryptography我也得到了这个错误。

我读的地方，我应该尝试：pip install --global-option build_ext --global-option --compiler=mingw64 pyopenssl，和我：

可有人请告知有什么错？

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

我也有类似的问题，安装的libssl头文件，所以我可以编译Python模块：

sudo apt-get install libssl-dev
