pipx install doesn't prompt for credentials for private vcs url

Describe the bug Regular pipx install command doesn’t work for private vcs urls that require authentication. Running pipx install --spec git+https://<some_private_repo>.git <package_name> does not prompt the user for username and password. If the --verbose option is provided, it works fine.

How to reproduce Run above command using a private vcs url (e.g. github, gitlab, bitbucket) and do not use --verbose.

Expected behavior Should prompt user for credentials, even when --verbose is not used.

Environment

This is also an issue for private package feeds requiring credentials, eg an Azure artifacts feed

It neither prompts, or works with artifacts-keyring like pip does

I’m running into a similar issue when trying to install from a private registry or index-url (e.g., github/gitlab/artifactory/etc) that requires authentication.

In my case, I’m using keyring to store the credentials required, and pip will automatically use keyring if available. A typical pip based workflow would be python -m venv .venv && source .venv/bin/activate && pip install keyring && pip install -i https://authenticated.example.com/pypi/simple some-package-name.

In order to achieve something similar with pipx, pipx should have a mechanism to (pre?) inject packages (keyring, artifacts-keyring, etc) into an app’s venv before the app itself is installed.
