Installing packages in a python 3.6 environment fail due to PEP 517

[x] I am on the latest Poetry version.

Issue
A dependency uses MarkupSafe and our project must support python ^3.6.2. Since I updated to poetry 1.2.0, I can not use the python 3.6 environment anymore.
Installing MarkupSafe manually works, when I disable pep 517:
> poetry run python -m pip install --no-use-pep517 markupSafe==2.0.1
However, there is no option to disable pep 517 in poetry. Is there any other way to install such packages?
Errors
> poetry env use 3.6
> poetry -vvv install

Looks like the same error message as https://github.com/python-poetry/poetry/issues/6288, but in this case poetry is installed as recommended (i.e. not in the same venv)
It is not entirely the same error message. In #6288 it is a [Errno 2] No such file or directory, while we get `can't find 'main' module in ....
poetry is simply shelling out to pip here, it looks as though your pip is broken.
Similar issue in the pip repository pins the blame on debian - https://github.com/pypa/pip/issues/7946
I can believe that, though this wasn't a problem in poetry <1.2 - I'm guessing there's been a change in the way poetry invokes pip/which pip it uses? Any suggestions to work around this issue?
Poetry 1.2 makes use of PEP 517 for a variety of reasons -- there's not a way to disable it for our purposes. You can work around this by installing upstream pip and dropping the patched Debian version in your image -- pip install --upgrade --force-reinstall pip or similar, inside the Poetry environment. poetry self add pip@latest might also work without having to figure out where you installed Poetry.

Just tried out both the pip upgrade using pip install and with poetry self add as well. We're using a docker container for our CI with virtualenv creation set to false and it still failed. The error message I get is
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.9/site-packages/virtualenv/seed/wheels/embed/pip-22.2.2-py3-none-any.whl'
Are you installing Poetry into your system site-packages as well as your project? That looks like what I'd expect -- Poetry will be uninstalling its own dependencies out from under itself most likely. Your issue is not related to this thread -- instead it is #6398.
No luck with either /root/.local/share/pypoetry/venv/bin/pip install --upgrade --force-reinstall pip or poetry self add pip@latest - hitting the same error as above.

Sorry, the original error from my post that includes the Dockerfile.
I've done some digging and I'm not 100% sure why we're getting these issues, even with Python 3.6 built from source on Debian/Ubuntu. However, the unreleased 1.2 branch does have a behavior change that happens to mitigate this (by using the pip inside the target environment). However, it is very possible to not have a pip in the target environment, so I can't consider it to be a 100% complete fix.
More debugging has been done -- this is a consequence of Poetry attempting to use its own embedded pip (or rather the pip embedded in the virtualenv module) with an interpreter that that version of pip does not support. We are discussing strategies to resolve this both short-term in 1.2 and longer term now.
Thank you for looking into this! Very appreciated.
I also tried built python from source to narrow down the problem.
Poetry tries to run the following and fails:
/tmp/foo/.venv/bin/python /home/john/.local/lib/python3.10/site-packages/virtualenv/seed/wheels/embed/pip-21.3.1-py3-none-any.whl/pip install --disable-pip-version-check --prefix /tmp/foo/.venv --no-deps MarkupSafe-2.0.1.tar.gz
Whereas works fine:
/tmp/foo/.venv/bin/python -m pip install --disable-pip-version-check --prefix /tmp/foo/.venv --no-deps MarkupSafe-2.0.1.tar.gz
The second attempt also uses pip 21.3.1.
So the interpreter seems to support the used version.
Here is a bit more detailed output and the pip versions. Both commands should have the same parameters and are the once also used by poetry.

poetry 1.2.1 doesn't default to the embedded pip. So for those who were hitting this it's likely worth trying again
I had a similiar issue with pyrsistent 0.16.1, poetry 1.2.1 solved it
