我正在尝试安装"fabric"。我尝试使用"pip安装结构"，但在尝试安装"pycrypto"时安装失败
我看到它正在获取2.6.1版本。我尝试安装较低版本，但我得到了同样的错误。
"sudo easy_install fabric"也引发了同样的错误。
我还安装了gmplib。我在这些地方有lib文件/usr/lib/libgmp.dylib/usr/local/lib/libgmp.dylib
pip install fabric

这是我在执行"fab"时遇到的错误

安装xcode后使其正常工作。
pycrypto是在xcode安装后默认安装的，结构现在可以工作了。
（我应该在问题中提到我是MAC的新手）
