篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了安装pywin32时,出现找不到python27注册信息的解决方法相关的知识,希望对你有一定的参考价值。
1. 检查一下注册表是否存在python其它版本的信息
方法:
1)在命令行中输入regedit打开注册表
2)在HKEY_CURRENT_USER\\Software中找一下是否存在python注册信息,如果存在,检查一下是否是python27版本,且是否包含下面两个节点
再检查一下其对于的安装路径是否正确。如果不知道如何检查,可以把python节点信息右击选择删除。如果python注册信息不存在,这里就不用操作了。
2.新建register.py文件,复制如下代码保存在D盘根目录下,cmd命令行运行 python register.py,当输出“python 2.7 is already registered”就ok了
(python27使用正常,无需修改任何内容)

3.执行后再检查一下注册表。python27的注册信息已经存在了
4. 再次安装pywin32-220.win32-py2.7.exe,结果安装成功
