摘要：Python version 2.7 required, which was not found in the registry

安装PIL库的时候，直接提示：Python version 2.7 required, which was not found in the registry。如图： [img]http://files.jb51.net/file_images/article/201408/201482693530422.png?201472693551[/img] 大意是说找不到注册表，网上搜索解决方案。新建一个register.py文件写入代码：

[u]复制代码[/u] 代码如下:

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!"

启动命令切到register.py文件目录下执行: [img]http://files.jb51.net/file_images/article/201408/201482693610938.png?201472693619[/img] 重新安装PIL，错误解决，安装成功。如果是win7 64位的用户在安装Python 32位程序时，如果选择只为当前用户，以上问题不会出现。如果选择所有用户，就试着使用以上方法解决。提示其它版本解决方法类似。
