我的操作系统是win7 64bit,平时一直用的是python2.5.4的版本,因为今天需要用到python读取mysql数据库,不过网络上没有支持python2.5.4的64bit mysql包版本。所以换了python2.6,反正只是临时解决方案,写完程序之后还会换回来的。然后在使用过程中遇到一些问题。

先列一下软件下载的地址
python2.6 64bit下载:http://www.python.org/ftp/python/2.6/python-2.6.amd64.msi
MySQL-python-1.2.2.win-amd64-py2.6:http://www.codegood.com/download/3/


先后安装完毕之后,先打开IDEL准备测试一下
import MySQLdb

import MySQLdb

Traceback (most recent call last):
    File "", line 1, in
         import MySQLdb
    File "C:\Python26\Lib\site-packages\MySQLdb\__init__.py", line 34, in
        from sets import ImmutableSet
    File "C:\Python26\Lib\sets.py", line 85, in
        stacklevel=2)
    File "C:\Python26\lib\warnings.py", line 29, in _show_warning
        file.write(formatwarning(message, category, filename, lineno, line))
TypeError: idle_formatwarning_subproc() takes exactly 4 arguments (5 given)

居然连导入包都不能...... 太扯淡了,第一时间搜索了一下,得到解决方案.
解决办法来源:http://flo.nigsch.com/?p=62

修改 \Python26\Lib\site-packages\MySQLdb\__init__.py
第34行
#注释这一条语句 from sets import ImmutableSet
#添加以下语句.
ImmutableSet = frozenset

在第四十行添加一条
BaseSet = set


保存完毕,OK,测试一下
#!/usr/bin/env python
#coding=utf-8
import MySQLdb

conn = MySQLdb.connect (host = "localhost",
                                             user = "root",
                                             passwd = "root",
                                             db = "test")
cursor = conn.cursor ()
cursor.execute ( "SELECT VERSION()")
row = cursor.fetchone ()
print "server version:", row[0]
cursor.close ()
conn.close ()


运行结果,一切正常,开始工作了,等写完测试程序后再来研究这个bug究竟是怎么回事.
