Warning

Warning

The authors of pip do not condone the use of this package. Relying on pip’s internals is a dangerous idea for your software as they are broken intentionally and regularly. This package may not always be completely updated up PyPI, so relying on it may break your code! User beware!

Installation

Install from PyPI:

$ pipenv install --pre pip-shims

Install from Github:

$ pipenv install -e git+https://github.com/sarugaku/pip-shims.git#egg=pip-shims

Summary

pip-shims is a set of compatibilty access shims to the pip internal API. pip-shims provides compatibility with pip versions 8.0 through the current release (18.x). 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.

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')

Available Shims

pip-shims provides the following compatibility shims:
