在OSX 10.6上为Python安装MySQLdb - 创建.egg时出错

Question

我在Snow Leopard上运行的是32位的Python 2.7，安装了64位的MySQL，以避免不同位数之间的冲突。不过，我在安装MySQLdb时还是遇到了问题。

我按照这个和其他一些网上的指南操作，但还是没有进展。安装时我看到的输出是：

有没有人知道我哪里出错了？

很可能你曾经在使用 sudo 命令运行 python setup.py 的时候，导致现在你的 dist 文件夹属于根用户（root）。你需要先清空你构建目录下的 dist 子文件夹，然后再重新运行：

sudo rm -rf ./dist
ARCHFLAGS='-arch x86_64' python setup.py install

如果在最后的安装步骤中出现权限错误，你可能需要在 sudo 下运行 install 步骤：

sudo bash
export ARCHFLAGS='-arch x86_64'
/path/to/same/python2.7 setup.py install
exit

不过，如果没有必要的话，最好还是不要这样做。
