如何解决在python 3.9中安装chatterbot的问题
我尝试在Windows 10中下载chatterbot程序包，但始终显示错误。 我正在使用python 3.9并尝试将其安装在虚拟环境中。
我最近下载了Microsoft Visual C ++ 2019，我认为该错误是由C ++的构建工具引起的，因为我可以在下面的一行之一中看到它
这些是我的命令：
(virtual_assistant) C:\Users\DELL\my_envs>pip install chatterbot

请帮助我找出问题所在
解决方法
Python 3.9是截至目前（2020年11月）的python的新版本，尚未打包所有轮子。
尝试使用具有轮子的python 3.7。如果必须使用更高版本，则需要install from the source code。
