See https://pip.pypa.io/en/latest/user_guide/#using-pip-from-your-program - importing functions from pip is not supported. In this case, setuptools (specifically pkg_resources) probably has the functionality you need.

@codingCoffee No, that's explicitly not the right thing to do. Please don't do this, we will not support such usage.

@pfmoore, I agree, that it's a bad practice. I just meant the comment as a quick fix to the problem

@08zhangyi thats horrible - pip has json output for that which gives correct parsed results, please edit/remove the bad code

@codingCoffee same for your bad example - because people do actually use bad examples because they are the first thing they find that works

Hi @Great-Li-Xin!

You can use pkg_resources.working_set for getting the same information. It's part of setuptools, which is probably already installed on your system. That is a supported way for getting the exact same information. Using pip's internal functions is not supported.

import pkg_resources

dists = [d for d in pkg_resources.working_set]
# Filter out distributions you don't care about and use.

The function @codingCoffee mentioned has moved into an pip._internal name, to signify that usage of the same is not supported and may change anytime without notice. It is strongly discouraged to use it.

@08zhangyi that seems to be a very fragile way to do this. As @RonnyPfannschmidt points out, there's JSON output pip list --format=json that is much better suited for consumption by computers.


@Great-Li-Xin feel free to close this issue if your concerns are addressed. :)

From pip 10.0.0 on pip.get_installed_distributions does not work any more. I suggest to use pkg_resources.working_set instead as discussed here: pypa/pip#5243. Works fine for me...

As discussed in this thread: pypa/pip#5243
use of the functions inside pip._internal is strongly discouraged. As
such I have replaced this functions usage with the pip maintainers
recommended solution.

For pip 10 use from pip._internal.utils.misc import get_installed_distributions

To restate, this function has moved into pip._internal namespace, to signify that usage of the same is not supported and may change anytime without notice. It is strongly discouraged to use it.

Downgrade pip to 9.0.3 will fix this problem

pip install pip==9.0.3

@Yemsheng Downgrading to pip 9.0.3 is a way to work around this issue; you're essentially pinning yourself to an older version of pip until the underlying project changes itself to use a supported way to perform these actions.

dune-community-bot pushed a commit to dune-mirrors/dune-common that referenced this issue Jun 30, 2018
pip 10 moved several interfaces to an internal package, causing our pyversion.py script to fail.
This patches fixes the issue by getting installed distributions directly from setuptools, as
suggested in pypa/pip#5243.

See merge request core/dune-common!540

  pip.get_installed_distributions() is in internal function
  that was never meant to be externally called and has since
  been locked out by external functions.

  Lets switch over to the supported function in setuptools
  pkg_resources.get_distribution() to search the installed
  packages.

  See: pypa/pip#5243
  Fixes: 255

well i believe the suggested solution is best for me
So i can remove the tight couple with pip

import pkg_resources

dists = [d for d in pkg_resources.working_set]
