【问题描述】：

我正在尝试在 PyCharm 中使用 ChatterBot，但是在运行一个简单的示例程序时：

from chatterbot import ChatBot

chatbot= ChatBot("Josie")

from chatterbot.trainers import ListTrainer

conversation = ["Hello","Hi There",
               "How are you doing?", "I'm doing great.",
               "That is good to hear", "Thank you.", "You're welcome."]

trainer = ListTrainer(chatbot)

trainer.train(conversation)

response = chatbot.get_response("Good morning!")
print (response)

我收到了这个运行时错误：

/Users/williams/PycharmProjects/test_1/venv/bin/python /Users/williams/PycharmProjects/test_1/test_1.py

 Please use the NLTK Downloader to obtain the resource:

 For more information see: https://www.nltk.org/data.html

 Attempted to load corpora/stopwords.zip/stopwords/

我运行了以下代码：

import nltk
nltk.download('stopwords')

但仍然收到错误消息“SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败：无法获取本地颁发者证书 (_ssl.c:1076)>”

我尝试过使用/Applications/Python\ 3.7/Install\ Certificates.command，但我再次收到错误：

我快疯了，想弄清楚这一点。任何帮助将不胜感激。
