如何解决在Python上安装chatterbot时出错
每当我尝试使用pip install ChatterBot安装ChatterBot时，总是会在此部分显示错误：
Collecting spacy<2.2,>=2.1 Using cached spacy-2.1.9.tar.gz (30.7 MB) Installing build dependencies ... error
我尝试过多次重新安装python，但似乎无济于事。 我也尝试过单独下载spacy，但只会给出相同的错误
我正在使用Windows 10，Python版本3.8.5和pip版本20.2.4。
Here's the error that I got from my log file:

如果有人可以帮助我，我将不胜感激
解决方法
我只是通过降级到 chatterbot 1.0.4 才成功
1. pip install -U setuptools pip wheel
2. pip install -U chatterbot==1.0.4
我使用的是 Windows 10，python 3.8.7 - 64 位，pip 21.0.1，
注意：使用 64 位 python，spacy 不会在 32 位 python 上安装/工作。
