安装第三方库出现 Python version 2.7 required, which was not found in the registry

建立一个文件 register.py 内容如下. 然后执行该脚本.

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()
