How to validate pip's --extra-index-url?

Question

I am unable to find certain packages that should be found from a local package index that I've defined with the --extra-index-url in my global pip.ini file.

How can I validate that my pip is using this properly? In my scenario I'm using a virtual environment.

I have tried pip config list because it sounded promising in pip help , but I get nothing as an output.

Try installing a module that doesn't exist:

pip install --extra-index-url=https://example.com made-up

In my case (aside from a lot of errors) I also get:

Looking in indexes: https://pypi.org/simple, https://example.com
Collecting made-up
  Could not find a version that satisfies the requirement made-up (from versions: )
  No matching distribution found for made-up

If you are setup correctly, you should see the extra repo URL in the output. If you are running with defaults the "Looking in indexes" line is not shown.
