我在将robotframework版本从3.2.2更新到4.1.1后看到此消息也许有人遇到过类似的问题，并有解决方案?我想这与另一个问题有关https://github.com/nokia/RED/issues/413
这里是Traceback:

from robot_hub import RobotHub

if __name__ == '__main__':
app.hub = RobotHub(app)

我发现包rfhub v 1.0.1 (https://pypi.org/project/robotframework-hub/)不t support robotframework version > 4.0. There isnt所需的方法在htmlwriter.py
