运行PythonWin时出错

Question

我想为ArcGIS（10.4.1版）编写脚本。为了这个目的，我打算用Python。但在安装之后，当我运行程序时，会弹出Python回溯：

Traceback (most recent call last):
  File "C:\Python27\ArcGIS10.4\Lib\site-packages\pythonwin\pywin\framework\intpyapp.py", line 181, in InitInstance
    import interact

    import winout

    import pywin.scintilla.view

    line, lineno = self._load_keys(subsection, fp, lineno)
  File "C:\Python27\ArcGIS10.4\Lib\site-packages\pythonwin\pywin\scintilla\config.py", line 270, in _load_keys
    sc, flag = keycodes.parse_key_name(key)
  File "C:\Python27\ArcGIS10.4\Lib\site-packages\pythonwin\pywin\scintilla\keycodes.py", line 91, in parse_key_name
    return vk, flags | this_flags
TypeError: unsupported operand type(s) for |: 'int' and 'NoneType'

我怎样才能解决这个问题？你知道吗
