在windows環境中（win7），建立虛擬環境，django建好模型準備遷移資料，執行命令：，出現如下錯誤：

提示 No module named MySQLdb，百度了一下說需要：pip install mysqlclient，然後執行該命令

(maiziblog) D:\workspace\blog_project>pip install --upgrade wheel
Requirement already up-to-date: wheel in d:\workspace\maiziblog\lib\site-packages

(maiziblog) D:\workspace\blog_project>mysql version
ERROR 1045 (28000): Access denied for user 'ODBC'@'localhost' (using password: NO)

安裝不上，後來我通過如下途徑的到解決，在http://www.codegood.com/archives/129 下載安裝 MySQL-python-1.2.3.win-amd64-py2.7.exe
安裝完成之後問題完美解決：
