在注册表中无Python3.5安装路径的情况下安装pywin32-

当安装pywin32出现Python Version 3.5 required which was not found in the registry的时候表面注册表中没有Python3.5的安装路径。
我出现这种情况是因为我直接用的Anaconda所以注册表没有注册
解决办法：
1. 先在注册表中写入Python3.5的安装路径。我在网上找到了注册表注册的代码贴出来供大家使用。

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()

2.然后在直接运行安装文件即可
