"AttributeError: 'dict' object has no attribute 'select'" when running CLI commands

gabrielmip commented 3 years ago

Hi there!

Issue

The CLI is raising exceptions at least when it is run without any parameters and with the --help parameter, but probably with other parameters too. Poetry reported the line number where the exception was raised:

Creating virtualenv worker-scheduler-dZdMRvTq-py3.9 in /home/gabriel/.cache/pypoetry/virtualenvs

  AttributeError

  'dict' object has no attribute 'select'

  at /usr/lib/python3.9/site-packages/virtualenv/run/plugin/base.py:14 in entry_points_for
      10│     _ENTRY_POINTS = None
      11│ 
      12│     @classmethod
      13│     def entry_points_for(cls, key):
    → 14│         return OrderedDict((e.name, e.load()) for e in cls.entry_points().select(group=key))
      15│ 
      16│     @staticmethod
      17│     def entry_points():
      18│         if PluginLoader._ENTRY_POINTS is None:

To be clear, virtualenv still raises the exception when I run virtualenv directly, without poetry's interference.

Environment

Provide at least:

OS: arch linux (manjaro)
uname -r: 5.13.13-arch1-1
Python Version: 3.9.6
Virtualenv version: 20.7.2

This sounds like a problem of having an incorrect dependency of importlib-metadata. What python packages have you installed and how did you install those?

gabrielmip commented 3 years ago

I mostly install system-wide packages using the operational system's package manager, but, looking at the bash history, I have installed a bunch of other packages directly by pip:

ansible-lint
autopep8
cli_helpers
dephell
docker-compose
flake8
flake8 pylint
flower
ipython
jedi-language-server
mycli
neovim
pgcli
pyls-mypy
pymysql
pynvim
python-language-server[all]
six
sphinx
sphinxcontrib-httpdomain
sqlparse
whitenoise

The import-metadata version is 0.23. The complete output of pip list follows:

Seems either the OS or some of those installs messed up your installation because this requirement is not satisfied:

https://github.com/pypa/virtualenv/blob/main/setup.cfg#L43

This is why I always recommend you use https://pypa.github.io/pipx/installation/ via https://pypi.org/project/pipx-in-pipx/

I can just mention that I ran across a similar issue on Manjaro now, after trying to get the backports package installed I finally succeeded by the more brutal deletion of ~/.local/lib/python3.9/, which I suppose also means I will never learn if I had precisely the same issue as OC or something vaguely relevant.

I guess my comment just states that it seems we manage to run into this issue at times on Arch based distros.
