我最近从10.6升级到Mac OS X 10.7。
我决定使用Python 2.7。
但是当我尝试安装MySQLdb模块来运行Django时,它失败了:
$ sudo pip install MySQL-python

----------------------------------------
原因是我不再拥有llvm-gcc
或gcc
二进制文件。
我尝试将XCode从3.something升级到4.3.2,但它没有帮助。它是一个简单的应用程序,它不会/usr/bin
填充llvm-gcc
。
我做错了什么?

在Xcode 4.3的Preferences
菜单中,选择Downloads
,然后安装Command Line Tools
。

让符号链接为我工作:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
