我是 Python 新手，在构建 MySQLdb 时遇到问题，试图让 Google AppEngine SDK 运行。我刚刚从 Snow Leopard 升级到 Mountain Lion，并安装了最新的 XCode (4.4)
我已经下载了http://sourceforge.net/projects/mysql-python/
python setup.py build
我在终端中得到以下输出

以下两个目录都存在，我不知道如何解决 clang 无法执行的问题...
/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
/usr/local/mysql/include
似乎系统正在抱怨找不到clang，它包含在Command Line Tools of Xcode。你也安装了这个工具吗？
可以通过安装
