python - 抑制 cmd 警告消息

Question

进入外壳时，我总是收到以下警告消息cmd2：

Desktop david$ python3 client.py
Readline features including tab completion have been disabled because
no supported version of readline was found. To resolve this, install
pyreadline on Windows or gnureadline on Mac.

这是我知道的，我不是在寻找或解决这个问题。是否有一个选项可以抑制此错误消息cmd2？顺便说一句，这里是警告消息的来源：https ://github.com/python-cmd2/cmd2/blob/f5af7d32fb468012f793eb039e05a86292e0e5bf/cmd2/cmd2.py#L132-L146 。
