pywintypes.com_error: (-2147221008, 'CoInitialize has not been called.', None, None)

Question

当我按原样尝试运行这段代码时，我得到了这个错误 "IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch) pywintypes.com_error: (-2147221008, 'CoInitialize has not been called.', None, None)" ，但是如果我单独运行 stp_tracker 它工作正常，如果我运行单独通知 stp 它工作得很好。我感谢任何人的意见。谢谢

Answer 1

对此表示歉意，但在互联网上搜索后我发现了一些有用的东西。我早些时候遇到了相同的 post，并认为它是已弃用的信息，因为我在 pycharm 中的自动完成在键入 pythoncom.CoInitialize() 时没有拾取任何东西，所以这让我认为它是过时的信息。 Strive Sun 也解释了相同的信息

第一个：

import pythoncom

然后设置：

xl=win32com.client.Dispatch("Excel.Application",pythoncom.CoInitialize())

pywintypes.com_error: (-2147221008, 'CoInitialize has not been called.', None, None)

pywintypes.com_error: (-2147221008, 'CoInitialize has not been called.', None, None)

python

events
