python3.6无法安装PYWIN32的问题

原因是PYTHON3.6未在HKEY_CURRENT_USERSOFTWAREPythonPythonCore写入3.6的信息

解决方法一：把下面的文本中路径改成自己的py3.6的，另存为.reg，然后导入

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USERSOFTWAREPython]
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore]
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore3.6]
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore3.6Help]
@=""
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore3.6HelpPythonwin Reference]
@="C:\Python\Python36\Lib\site-packages\PyWin32.chm"
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore3.6InstallPath]
@="C:\Python\Python36"
[HKEY_CURRENT_USERSOFTWAREPythonPythonCore3.6PythonPath]
@="C:\Python\Python36;C:\Python\Python36\Lib\;C:\Python\Python36\DLLs\"

解决方法二：用下面PY脚本，3.X版本都可以通用，自动会添加当前版本的信息

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()
