Answer 1

让它工作 - 卸载所有 python，清除缓存，安装 python 3.7.2。

Answer 2

Reason: Chatterbot is indirectly using blis 0.2.4 And that version is not providing precompiled wheels for python 3.8.

To fix that issue:

• Uninstall the current python version; check the version type in cmd python --version
• Download and install python 3.7
• Then install chatterbot pip install chatterbot
