我在 Macbook Pro 上双启动了一个 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。

我还尝试使用 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不记得的事情，我想我什至尝试过下载一个 tar 文件，然后现在，当我运行 pip install cffi 时，我被告知它已经安装了。

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

我在执行 pip install cryptography 时也遇到了这个错误。

我在某处读到我应该尝试:pip install --global-option build_ext --global-option --compiler=mingw64 pyopenssl，我得到了:

有人可以告诉我哪里出了问题吗？

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:

最佳答案

我遇到了类似的问题并安装了 libssl 头文件以便我可以编译 python 模块:

sudo apt-get install libssl-dev

关于python - 无法安装 pyOpenSSL，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39525704/
