【问题标题】：Error installing PyCrypto on Mac 10.9.5在 Mac 10.9.5 上安装 PyCrypto 时出错

【问题描述】：

我正在尝试为 Python 3.4 安装 PyCrypto，但我遇到了 C 编译程序的问题。它说“错误：无法运行 C 编译程序”。有人知道如何解决吗？？

代码：

running build
running build_py
running build_ext
running build_configure
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... configure: error: in `/Users/briansabbath/Desktop/pycrypto-2.6.1':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details

【问题讨论】：

我尝试通过 home-brew 安装，但这是另一个问题，因为我在安装 homebrew 时遇到错误，并遵循其他不起作用的建议:(

【解决方案1】：

这可能表明你没有安装像 gcc 这样的 C 编译器。运行以下命令可能会有所帮助（命令行工具必须安装在 xcode 中）：

xcode-select --install

【解决方案2】：

对我有用的方法

brew install pip
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install pycrypto

您可以在 virtualenv 中运行它。如果您有更好的方法，请在下方留言！
