pipx install --update

[gsemet]

pipx install:

• install if missing.
• if available and in the right or wrong version (spec not respected), does nothing

pipx install --force:

• always reinstall, even if available and if spec respected

pipx update:

• always update, even when spec is respected
• if not installed, fail

pipx update --install:

• always update, even when spec is respected
• if not installed, install.

What I need is a command that will:

• if not install, install respecting the provided spec
• if installed but the spec is not respected, update to the spec, allowing downgrade
• if installed and spec is respected, does nothing, not even a network connectivity

Example:

$ pipx install --upgrade pylint<7

• if the current pylint venv respects <7, does nothing.
• If the current pylint venv does not respect <7, update
• if no pylint installed, install to version <7

On the network connectivity, this might be done with https://github.com/pypa/pipx/issues/1275 to allow pipx run do not try to perform any network connectivity when the spec is respected

Actually, this is also a feature I want. But I would suggest to align with pip install to use --upgrade and --upgrade-stragtegy as options instead.

Contributions are welcome.

@huxuan I'm interested in working on this, but I fail to see how pipx install --upgrade <package> would be any different than pipx upgrade <package>? Or is this just a convenience command to mirror the functionality of pip more closely? I suppose pipx install --upgrade would always install if not exists, whereas pipx upgrade would just error, but that's the only differing functionality between the two comands I can think of right now
