【问题描述】：

我正在使用带有最新 OS X 更新的 Mac。我试图在终端上安装 PyCrypto，但出现如下图所示的错误。我使用的命令是sudo pip install pycrypto。你能帮我解决这个问题吗？我该如何解决这个问题？感谢您的回答。

这是错误：

macfive:Desktop admin$ sudo pip install pycrypto

错误太大，无法全部复制。所以我只是复制了开头和结尾。

请复制粘贴错误文本而不是屏幕截图。
我已经更新了我的问题并添加了错误文本。
您可以从以下链接pypi.python.org/pypi/pycrypto 下载它并尝试使用python setup.py install 进行安装。使用自述文件了解更多详细信息。
我已经尝试过了，它不会工作。得到同样的错误。
虽然是在linux上，但是你看到了吗：gcc-4-2-failed-with-exit-status-1?

【解决方案1】：

您需要安装 Python 开发文件。我认为它会起作用。试试

apt-get install autoconf g++ python2.7-dev

或者

sudo apt-get install python-dev

上面的一个，然后下面一个

pip install pycrypto
