Windows 10 64位下安装python2模块MySQLdb（MySQL-python）遇到的坑

开始

在这儿下载了MSI安装包.

安装的时候需要python安装目录，配置信息在注册表里。

因为本地系统安装了两个版本的Python（2和3），手动修改的Python27安装目录。

HKEY_CURRENT_USER\Software\Python\Pythoncore\2.7\InstallPath

如果安装了一个版本的Python，可以使用Python脚本：

#
# script to register Python 2.0 or later for use with win32all
# and other extensions that require Python registry settings

import sys

from _winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
installpath, installpath, installpath
)

def RegisterPy():
try:
reg = OpenKey(HKEY_CURRENT_USER, regpath)
except EnvironmentError as e:
try:
reg = CreateKey(HKEY_CURRENT_USER, regpath)
SetValue(reg, installkey, REG_SZ, installpath)
SetValue(reg, pythonkey, REG_SZ, pythonpath)
CloseKey(reg)
except:
print "*** Unable to register!"
return
print "--- Python", version, "is now registered!"
return
if (QueryValue(reg, installkey) == installpath and
QueryValue(reg, pythonkey) == pythonpath):
CloseKey(reg)
print "=== Python", version, "is already registered!"
return
CloseKey(reg)
print "*** Unable to register!"
print "*** You probably have another Python installation!"

if __name__ == "__main__":
RegisterPy()

报错

ImportError DLL load failed: %1 不是有效的 Win32 应用程序

原因是操作系统是win10 64位，而安装包用的win 32位。

找64位安装包

下载地址：

https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python

pip install wheel
pip uninstall MySQL-python # 先卸载掉原来的Mysql-python
pip install MySQL_python-1.2.5-cp27-none-win_amd64.whl
pip install mysqlclient-1.3.12-cp27-cp27m-win_amd64.whl

可能在windows下还报其他错误，可能没有安装Microsoft Visual C++ 2008 2010。
