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：

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：

复制代码 代码如下:

import sys

from _winreg import *

# tweak as necessary

version = sys.version[:3]

installpath = sys.prefix

regpath = "SOFTWAREPythonPythoncore%s" % (version)

installkey = "InstallPath"

pythonkey = "PythonPath"

pythonpath = "%s;%sLib;%sDLLs" % (

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:

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。
