onepm 24.2

onepm
Picks the right package manager for you.
Don't make me think about which package manager to use when I clone a project from other people. OnePM will pick the right package manager by searching for the lock files and/or the project settings in pyproject.toml.
This project is created in the same spirit as @antfu/ni.
Supported package managers: pip, pipenv, poetry, pdm, uv
Install onepm
Install with pipx:
pipx install onepm

Or use pdm global install:
pdm add -g onepm

If the package manager agent is pip, OnePM will enforce an activated virtualenv, or a .venv under the current directory.
Shims for Package Managers
OnePM also provides shim for the package managers like corepack,
so you don't need to install package managers yourself. To enable it, install OnePM with shims extra:
pipx install --include-deps onepm[shims]

OnePM reads the package-manager field under [tool.onepm] table in pyproject.toml, and install the required package manager with the correct version in an isolated environment.
[tool.onepm]
package-manager = "poetry"

Or you can restrict the version range:
[tool.onepm]
package-manager = "poetry>=1.1.0"

For Python package management, OnePM is all you need.
