描述

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

研究方向
The issue requests a new ` upgrade` flag for `pipx install` that behaves as described. There are 2 comments but no maintainer response. The codebase is in Python; the relevant files are likely the CLI module and the install/update logic. Investigate how the existing `install` and `update` commands handle version specifiers and determine where to add the new flag. The implementation should handle three cases: no install, installed but spec not respected, installed and spec respected (do nothing). Consider downgrade allowed. Look at the current `pipx install force` and `pipx update` implementations to reuse logic.
