Pre-requisites for "requirements.txt"?

[jrs477]

I tried to follow your example on Github but have some very basic questions, coming from a novice background.

I saved the file "requirements.txt" in a directory and then in the terminal tried to run:
pip install -r requirements.txt

The following message was returned:

  Could not find a version that satisfies the requirement auth2==1.0 (from -r requirements.txt (line 1)) (from versions: )

No matching distribution found for auth2==1.0 (from -r requirements.txt (line 1))

What other basic steps would I need to take before running the "pip install" command?

Thanks very much for your help!
