    根据报错信息找到 input.py 文件

        async def type(self, text: str, options: Dict = None, **kwargs: Any
                       ) -> None:
            options = merge_dict(options, kwargs)
            print("input options", options)  # 做的参数打印信息
            delay = options.get('delay', 0)
            for char in text:
                print("char step-->", char)
                if char in keyDefinitions:
                    print("if char key_definitions", char)  # 做的参数打印信息
                    await self.press(char, {'delay': delay})
                else:
                    print("else char -->", char)  # 做的参数打印信息
                    await self.sendCharacter(char)
                if delay:
                    await asyncio.sleep(delay / 1000)
