环境：

python3.6.2  + win10

 

指令如下：

pip install chatterbot

然后报错。

Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

 

尝试装一个低版本的，然后解决。

 

解决方案 

pip install chatterbot==1.0.1

可以解决，原因可能是版本不匹配导致？
