Installation
Install from PyPI:
$ pipenv install pip-shims
Install from Github:
$ pipenv install -e git+https://github.com/sarugaku/pip-shims.git#egg=pip-shimsSummary
pip-shims is a set of compatibilty access shims to the pip internal API. pip-shims provides compatibility across several pip releases. The shims are provided using a lazy import strategy by hacking a module by overloading a class instance’s getattr method. This library exists due to my constant writing of the same set of import shims across many different libraries, including pipenv, pip-tools, requirementslib, and passa.
Pip Compatibility
Due to the fact that pip has adopted calver, this project provides shims for pip releases up to 2 years. pip earlier than that period MAY work but the compatibility isn’t guaranteed by the continous integration. For example, the support for pip==20.0 will be dropped at 1/1/2023.
Usage
Importing a shim
You can use pip-shims to expose elements of pip’s internal API by importing them:
>>> from pip_shims import Wheel
>>> mywheel = Wheel('/path/to/my/wheel.whl')Resolving Dependencies
You can resolve the dependencies of a package using the shimmed resolver interface:
>>> from pip_shims.shims import resolve, InstallRequirement
>>> ireq = InstallRequirement.from_line("requests>=2.20")
>>> results = resolve(ireq)
>>> for k, v in results.items():
... print("{0}: {1!r}".format(k, v))
