源码安装出现下面报错，暂不推荐

最简单的方法就是下载二进制文件

查看python在注册表的路径

[HKEY_CURRENT_USERSoftwarePythonPythoncore3.6InstallPath]
@="C:\Python26"
  
[HKEY_CURRENT_USERSoftwarePythonPythoncore3.6PythonPath]
@="C:\Python26;C:\Python26\Lib\;C:\Python26\DLLs\"

安装pywin32出现Python Version 3.6 required which was not found in the registry，表示注册表里没有python3.6的安装路径，出现这个问题是因为我是直接从另一台电脑拖过来的，不是正规安装

在注册表中写入python3.6的安装路径

解决方法

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() 

然后再运行pywin32安装文件即可
