無法安裝 pyOpenSSL

Question

我在 Macbook Pro 上雙啟動了 Windows 10 分區：Mac：El Capitan（64 位） Windows：Windows 10 64 位，用胖文件系統格式化

在 Windows 上，我安裝了 cygwin 和 Python 2.7。 通過cygwin，我安裝了pip和gcc。

我還嘗試使用http://www.lfd.uci.edu/~gohlke/pythonlibs/#cffi安裝 cffi，但是當我運行 pip install cffi-1.8.2-cp27-cp27m-win_amd64.whl ，出現錯誤: cffi....whl is not supported on this platform 。 然后我嘗試了很多我不記得的東西，我想我什至嘗試下載一個 tar 文件，然后現在，當我運行 pip install cffi 時，我被告知它已經安裝了。

然后我運行了pip install pyOpenSSL ，但是，我收到了這個錯誤：

 gcc -fno-strict-aliasing -ggdb -O2 -pipe -Wimplicit-function-declaration -fdebug-prefix-map=/usr/src/ports/python/python-2.7.10-1.x86_64/build=/usr/src/debug/python-2.7.10-1 -fdebug-prefix-map=/usr/src/ports/python/python-2.7.10-1.x86_64/src/Python-2.7.10=/usr/src/debug/python-2.7.10-1 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/include/python2.7 -c build/temp.cygwin-2.6.0-x86_64-2.7/_openssl.c -o build/temp.cygwin-2.6.0-x86_64-2.7/build/temp.cygwin-2.6.0-x86_64-2.7/_openssl.o

當我執行pip install cryptography時，我也遇到了這個錯誤。

我在某處閱讀了我應該嘗試的內容： 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.

有人可以請告知有什么問題嗎？？

更新：通過cygwin安裝mingw64x86_64-openssl: OpenSSL encryption library for Win64 toolchain ，並運行pip install pyopenssl ，我得到：

我有一個類似的問題並安裝了 libssl 頭文件，所以我可以編譯 python 模塊：

sudo apt-get install libssl-dev
