Python mysqldb在Mac OSX 10.6上无法工作

Question

我正在使用Python 2.7，想要在MySQL数据库上运行一个Django项目。

我已经下载了mysqldb，并按照这个链接的指南进行了操作：http://cd34.com/blog/programming/python/mysql-python-and-snow-leopard/

但是当我尝试运行Django项目时，出现了以下错误信息：

我还尝试了这个链接的内容：http://whereofwecannotspeak.wordpress.com/2007/11/02/mysqldb-python-module-quirk-in-os-x/，在MySQL的库目录和其他地方之间建立了链接……

求助！

Answer 1

你需要把MySQL客户端库添加到LD_LIBRARY_PATH这个环境变量里。

Answer 2

我最后通过使用Mac Ports安装了Python 2.7，并用Mac Ports安装了mysqldb，之后就简单多了，问题也解决了。
