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

最近在看关于DHT网络爬虫的相关东西，然而DHT爬虫好多案列都是用的python来写的。没办法就开始去学习下python。

今天在本地搭建python的时候，安装MySQL-python-1.2.4b4.win32-py2.7 出现 错误：python version 2.7 required,which was not find in the registry

 当时我就吓尿了，我明明安装了python啊，还提示我没有找到。  谷歌之后才知道因为我的操作系统是win7 64位导致安装python的时候注册表没有写入对应的位置。

 

 解决办法如下：

  1.新建一个reg.py，输入如下代码

01#

02# script to register Python 2.0 or later for use with win32all

03# and other extensions that require Python registry settings

12import sys

13  

14from _winreg import *

15  

16# tweak as necessary

17version = sys.version[:3]

18installpath = sys.prefix

19  

20regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)

21installkey = "InstallPath"

22pythonkey = "PythonPath"

23pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (

24    installpath, installpath, installpath

25)

26  

27def RegisterPy():

28    try:

29        reg = OpenKey(HKEY_CURRENT_USER, regpath)

30    except EnvironmentError as e:

31        try:

32            reg = CreateKey(HKEY_CURRENT_USER, regpath)

33            SetValue(reg, installkey, REG_SZ, installpath)

34            SetValue(reg, pythonkey, REG_SZ, pythonpath)

35            CloseKey(reg)

36        except:

37            print "*** Unable to register!"

38            return

39        print "--- Python", version, "is now registered!"

40        return

41    if (QueryValue(reg, installkey) == installpath and

42        QueryValue(reg, pythonkey) == pythonpath):

43        CloseKey(reg)

44        print "=== Python", version, "is already registered!"

45        return

46    CloseKey(reg)

47    print "*** Unable to register!"

48    print "*** You probably have another Python installation!"

49  

50if __name__ == "__main__":

51    RegisterPy()

保存到任意位置，然后用 用在cmd下 执行如下命令。---前提是配置好了python的环境变量

1python reg.py

执行后会看到显示注册成功，如图。

再进行MySQL-python-1.2.4b4.win32-py2.7 安装程序，就能一路顺畅了！
