log檔如下:

試試 Python3.7 64bit 裝 1.04版chatterbot

pip install chatterbot ==1.0.4

打了上述的指令會出現這樣的錯誤：
ERROR: 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.

在網路上有找到在後面多打了「--ignore-installed」如下:

pip install chatterbot==1.0.4 --ignore-installed

仍有錯誤訊息，不過最後有顯示成功安裝了

這個一樣會顯示上面的錯誤
