pywin32找不到python怎么解决
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_USERSoftware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)

import sys
from _winreg import *
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
regpath = "SOFTWAREPythonPythoncore\%s" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%sLib;%sDLLs" % (
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()
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。
