New version breaks docopt + pyjwkest

[ian-nicholls2-NHSD]

Issue

Even though poetry downgrades to the version we require - some of the other libraries fail to install

now:

...
Collecting virtualenv<21.0.0,>=20.26.6
  Downloading virtualenv-20.34.0-py3-none-any.whl (6.0 MB)
...
  - Downgrading virtualenv (20.34.0 -> 20.33.0)
...
  ModuleNotFoundError
  No module named 'virtualenv.discovery.info'
  at .venv/lib/python3.9/site-packages/virtualenv/discovery/py_info.py:663 in _possible_base
Cannot install docopt.
...
  ModuleNotFoundError
  No module named 'virtualenv.discovery.info'
  at .venv/lib/python3.9/site-packages/virtualenv/discovery/py_info.py:663 in _possible_base
Cannot install pyjwkest.
...

working:

...
Collecting virtualenv<21.0.0,>=20.26.6
  Downloading virtualenv-20.33.1-py3-none-any.whl (6.1 MB)
... 
  - Downgrading virtualenv (20.33.1 -> 20.33.0)
...
  - Installing docopt (0.6.2)
...
  - Installing pyjwkest (1.4.2)

Environment

Provide at least:

• OS: Ubuntu 24

• Shell: bash

• Python version and path: 3.9.21

• pip list of the host python where virtualenv is installed:

How do I reproduce this exactly? If this is a Github Action, could you share a link? I feel like the report is incomplete.

Have a pyproject.toml that wants docopt and pyjwkest

I've got a workaround of:

  poetry install --no-root || poetry install --no-root

It works on the second pass as virtualenv is already downgraded to a version that "works" for those two old packages.

It would be nice if poetry retried (or at least an option to retry) failed ones after doing up/downgrades...
