windows-7 - windows7上，python2.7操作ie浏览器时，PAM30报错：pywintypes.com_error?

问题描述

问 题

如果在运行如上代码前，先打开一个 ie 浏览器，就正常运行，不会报错。
但是，如果不事前打开一个 ie 浏览器，直接运行如上代码，就会报错。
请大家看看是什么原因？
怎么弄好呢？

环境：
windows7 64位
python 2.7.12 32位
代码：

from PAM30 import PAMIE  
def d():  
  ie = PAMIE()  
  ie.navigate('http://pamie.sourceforge.net/pamieform.html')  

报错信息如下：

Traceback (most recent call last):
  File "D:/jianguoyun/pythonProgrames/myModule/test/pamieTest/pamie-f.py", line 37, in <module>
d()
  File "D:/jianguoyun/pythonProgrames/myModule/test/pamieTest/pamie-f.py", line 9, in d
ie = PAMIE()
  File "D:\jianguoyun\pythonProgrames\myModule\PAM30.py", line 68, in __init__
self._ie = win32com.client.dynamic.Dispatch('InternetExplorer.Application')
  File "D:\Python27\lib\site-packages\win32com\client\dynamic.py", line 127, in Dispatch
IDispatch, userName = _GetGoodDispatchAndUserName(IDispatch,userName,clsctx)
  File "D:\Python27\lib\site-packages\win32com\client\dynamic.py", line 114, in _GetGoodDispatchAndUserName
return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File "D:\Python27\lib\site-packages\win32com\client\dynamic.py", line 91, in _GetGoodDispatch
IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)
pywintypes.com_error: (-2147221164, '\xc3\xbb\xd3\xd0\xd7\xa2\xb2\xe1\xc0\xe0', None, None)

解决方案

导入如下注册信息，就可以正常调用了：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREWow6432NodeClassesCLSID{0002DF01-0000-0000-C000-000000000046}LocalServer32]
@=""C:\Program Files (x86)\Internet Explorer\iexplore.exe""

[HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{0002DF01-0000-0000-C000-000000000046}LocalServer32]
@=""C:\Program Files\Internet Explorer\iexplore.exe""
