我已尝试以下所有方法，但没有任何效果，错误仍然存在：

• pip install --upgrade setuptools --user python

• pip3 install --upgrade setuptools

• pip install cython

• pip install chatterbot==1.0.4

• pip install --upgrade pip setuptools wheel

• pip install git+git://github.com/gunthercox/ChatterBot.git@master

• pip install wheel cython

有什么想法吗？谢谢。

PyPi 上的可用信息显示 ChatterBot 需要：Python >=3.4，<=3.8. This means there's no support for your Python 3.10.

您可能需要降级到 Python 3.8 才能使用此软件包。请参阅https://pypi.org/project/ChatterBot/#data
