windows pip install MySQL-python

环境，windows64位下，python版本是2.7.11，因为操作数据库需要安装mysql-python，所以直接命令行下，

命令：pip install mysql-python

报错：

_mysql.c(42) : fatal error C1083: Cannot open include file: 'config-win.h': No s
uch file or directory

error: command 'C:\\Program Files (x86)\\Common Files\\Microsoft\\Visual C++ for
Python\\9.0\\VC\\Bin\\cl.exe' failed with exit status 2

起初以为需要安装VC for python，，，下载后还是不行

后来直接下载源文件mysql for python

命令：python set.py install

还是报错！！！

解决方案：

在这里下载对应文件

http://www.codegood.com/downloads

因为是我 windows64 位 所以MySQL-python-1.2.3.win-amd64-py2.7.exe

其他的在上面链接，按照自己的对应版本下载，双击即可

要想验证一下，可以这样做：

命令行下>>>import MySQLdb
直接打印>>>print MySQLdb
<module 'MySQLdb' from 'C:\Python27\lib\site-packages\MySQLdb\__init__.pyc'>

OK!，收工！！

error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27[/code] 
下载：Microsoft Visual C++ Compiler for Python 2.7

python version 2.7 required,which was not found in the registry

安装PIL-1.1.7.win32-py2.7的时候，不能再注册表中识别出来python2.7

方法：新建一个register.py 文件，把一下代码贴进去，保存

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()


按F5执行即显示：

显示“python 2.7 is already registered”

再安装setuptools的时候，就能自动识别出来python2.7了。

win7是 64的原因，在安装python（32位）时，如果选择只为当前用户，以上问题是不会出现的，如果选择所有用户，那就用上面的方法解决吧。
