python - pywinauto TypeError : item 2 in _argtypes_ passes a union by value, 不受支持

Question

我正在使用 pywinauto。

Python 3.7.6 pywinauto 0.6.8

我导入 pywinauto 模块没有问题，但有以下问题:

代码:

from pywinauto.application import Application
app = Application(backend="uia").start("thinkorswim.exe")

结果:

Traceback (most recent call last):
  File "C:\Users\willi\AppData\Local\Programs\Python\Python37\lib\ctypes\__init__.py", line 121, in WINFUNCTYPE
    return _win_functype_cache[(restype, argtypes, flags)]
KeyError: (<class 'ctypes.HRESULT'>, (<class 'ctypes.c_long'>, <class 'comtypes.automation.tagVARIANT'>, <class 'comtypes.LP_POINTER(IUIAutomationCondition)'>), 0)

During handling of the above exception, another exception occurred:

    prototype = WINFUNCTYPE(restype, *argtypes)
  File "C:\Users\willi\AppData\Local\Programs\Python\Python37\lib\ctypes\__init__.py", line 123, in WINFUNCTYPE
    class WinFunctionType(_CFuncPtr):
TypeError: item 2 in _argtypes_ passes a union by value, which is unsupported.

有 friend 可以帮忙吗？

这是已知的 Python 错误，已在更高版本(3.7.7+ 或 3.8.2+)中修复。在这里查看我的答案:Getting error while running a script which uses pywinauto

请注意，您可能需要全新安装较新的 Python。
