Cause: You don't need to install it in the first place

It seems that hmac and hashlib are available even if you don't install them ... Requirement already satisfied: setuptools in /usr/lib/python3.6/dist-packages (from hmac) (36.2.7) It is written. Once you know the result, you don't understand why you tried to install it for the time being.

Reference: python --Unsupported hash type error while installing hashlib using pip3 --Stack Overflow

I've been extremely confused with HMAC and Cloud9 for the first time, and even upgraded Python ...
