Mac OS X 10.8.3安装MySQLdb模块失败，求解脱。

[yibin001]

10.8.3中的Python有3个版本：2.5、2.6、2.7，默认是2.7，已通过defaults改为2.6了

测试：
>>> import MySQLdb
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "MySQLdb/__init__.py", line 19, in <module>
import _mysql
ImportError: No module named _mysql

为什么出现找不到_mysql这个模块？

看上去装到python2.7的Library下面了哦...我猜你sudo 下面的默认python 是2.7 估计也得改成2.6才行 btw，为什么不用virtualenv 或者virtualenvwrapper之类的东西呢

没有了解过。。我需要扫一下盲了。。。

[wtracyliu]

感觉virtualenv之类的确实不错... 最开始不知道，把系统自带的python下面的lib装的乱七八糟...自从用了这货，省心多了.. 楼主试试呗` virtualenv可以指定python版本 这样也不用去改系统自己的python，而且就算装错了打不了重新弄一个env

@wtracyliu
Thank u,我这就试试。

\mysqldb编译需要libmysqlclient 很奇怪你咋编译成功的
建议用pymysql代替之，纯python代码

说正题，你这个问题应该是没权限安装到系统目录里，所以其实安装过程是失败了的
运行python setup.py install的时候用sudo试试
或者建议virtualenv里折腾

需要下个东西，然后改下源码。。具体看下 http://www.zzhub.cn/article-detials/1
