描述

How would this feature be useful? If I want to run e.g. pipx run pylint, it would be nice if it could be tied to any version requirements I may have specified in my pyproject.toml file for installing pylint for development.

Describe the solution you'd like If something specified by pipx run is found in pyproject.toml's optional-dependencies, use that dependency specification when installing the tool into the temporary virtual environment. Probably would want to just grab the first requirement found instead of trying to be clever about it.

Describe alternatives you've considered I've considered not caring. 😉 Honestly it probably isn't worth worrying about this idea, but I at least wanted it written down after I thought about it in case anyone else also realized that when you are running a tool for a project there may be certain installation requirements for it.

研究方向
The issue proposes that `pipx run` should check the project's `pyproject.toml` for optional dependencies related to the tool being run and use that version constraint when installing it in a temporary virtual environment. The implementation should likely read the `pyproject.toml` in the current directory, look for `[project.optional dependencies]` or similar, and if the tool name matches a key, use the version specification. The feature request is low urgency and has had no recent activity; a newcomer should review pipx's source code for how it currently handles `pipx run` and the temporary environment creation (likely in `pipx/commands/run.py` or similar).
