Show pip download progress bar

[tae-soo-kim]

How would this feature be useful?

pip install shows a progress bar which is helpful when the package has a large size and downloading may take a long time. But pipx install omits that progress bar even with --verbose.

Describe the solution you'd like

Give users an option to show the progress bar. An easy way to do this is to pipe pip output into pipx.

Describe alternatives you've considered

PR welcome.

Does the linked branch above sufficiently address the issue?
Looks reasonable at a glance, wondering if they simply forgot to file a PR.

Stopping by to mention this issue hit me pretty hard, installing ansible and after trying --verbose --verbose --verbose was convinced pipx was broken... ended up checking slurm to see that the package download is just very slow tonight.

Would this be a valid solution? (Work in progress right now, but works with pipx install)

I found it difficult to pipe the progress bars themselves, but just showing the actual pip output during animation is possible, and might be considered a fix for this issue?

Please see for a draft of the solution: fluzzywuzzy:1069-pipe-pip-progress-bar

If it looks like a good start, I will finnish it up and open a PR.

I assume it might as well be integrated with all calls to animate for clarifying progress?

This is still very relevant.

I am trying to stream the pip output if --verbose is passed, but the main drawback is that pipx won't be able to capture the stdout/stderr and analyze the error. Folks may have check the traceback by themselves.
