windows下安装MySQL-python遇到的问题

执行安装命令

　　pip install MySQL-python

一、执行时会报一个错误

　　error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat).
　　Get it from http://aka.ms/vcpython27

解决方法：按提示去上面的网址下载并安装VCForPython27.msi

二、在执行安装命令时还会报错

　　error: command ‘C:\\Users\\Admin\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\cl.exe’ failed with exit status 2

解决方法：去 http://www.codegood.com/archives/129 下载执行 MySQL-python-1.2.3.win32-py2.7.exe

三、执行MySQL-python-1.2.3.win32-py2.7.exe时可能会报错：

　　python version 2.7 required,which was not found in the registry，大致意思是在注册表识别不出python2.7

解决方法：新建一个py文件，复制下面这段代码，执行该文件

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()

执行后会提示：

--- Python 2.7 is now registered!

在执行一次MySQL-python-1.2.3.win32-py2.7.exe，执行成功

执行安装命令：pip install MySQL-python

安装成功
