无法在蟒蛇中安装Chatterbot

问题描述

使用Python3.7在Anaconda中安装chatterbot时，我收到以下错误：

找到现有安装：PyYAML 3.13无法卸载‘PyYAML’。它 是一个安装了distutils的项目，因此我们不能准确地 确定哪些文件属于它，这将仅导致部分 卸载。

解决方案

使用conda环境安装chatterbot

• 使用Python3.7创建新的conda环境

conda create --name chatterbot_example python=3.7

• 激活环境：

source activate chatterbot_example

• 在环境内安装chatterbot和chatterbot-corpus：

pip install chatterbot
pip install chatterbot-corpus

• 创建如Chatterbot Documentation(example.py)所示的基础：

from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer

chatbot = ChatBot('Ron Obvious')

# Create a new trainer for the chatbot
trainer = ChatterBotCorpusTrainer(chatbot)

# Train the chatbot based on the english corpus
trainer.train("chatterbot.corpus.english")

# Get a response to an input statement
print(chatbot.get_response("Hello, how are you today?"))

• 运行程序：

python example.py

输出：
