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：

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，但再次出现错误：
我要疯了，想弄清楚这一点。任何帮助，将不胜感激。
