I am trying to implement your application but it gives me error in importing 4 modules. about django-facebook-messenger-bot-tutorial HOT 2 CLOSED

You should install requests. If you've downloaded the contents of the repository, you can find "pip install -r requirements.txt" in the list of commands that you have to run. This will install requests.

I have connected your application and interacts with facebook, but the chat application does not return any answers, I have dedicated this afternoon but I have been a long time with this error, just as you can give me a solution.
This is the message that returns me, the code is just as I have changed the tokens.
