poetry install fails without clear error while poetry export ... pip install -r requirements.txt works

I tried to use poetry install on Gitlab CI.

It fails to produce the virtual environment but no clear error message is given.

Just some

Connection pool is full, discarding connection: pypi.org. Connection pool size: 10

and then

/builds/master-tma/num-methods-turb/num_methods_turb does not contain any element

In contrast, pip install -r requirements.txt (with requirements.txt produced with poetry export) works well.

The results of a call of poetry install -vvv is there : https://gricad-gitlab.univ-grenoble-alpes.fr/master-tma/num-methods-turb/-/jobs/395825

Not a bug; in the future, please follow the issue template. It is important to do so to avoid wasting your time on a report that will never be actioned/is a duplicate, and to avoid contributors time trying to reproduce something with inadequate information.

In any case, PRs are welcome to improve the error message, but this was a usage error/is documented.

Nobody is suggesting that there are not real issues uncovered; however, the current behavior is as-designed and as (poorly) documented. You have been encouraged to open new issues, the reasons why that is preferred over this issue are very plainly communicated.

My answer is as long as it is to give historical context, to explain how we got to where we are, and how you can help make Poetry better through your issue reports as an end user. I think I’ve said all that is worth discussing on the topic – please do contribute if you wish, though issues and PRs, and please try to make those issues as clear and descriptive as possible.
