1.0.10 -> 1.1 regression: EnvCommandError: 'No module named setuptools' on Python 3.7

[gitpushdashf]

This may because it's installing a nested package. Python 3.8 doesn't have this issue but 3.7 does. I don't have a reduced test case yet. I'm hoping the traceback is helpful and someone knows what's going on from it. Python 3.7 and 3.8 are fine with Poetry 1.0.10, everything else being identical. Python 3.8 with Poetry 1.1.2 is fine as well, just not Python 3.7 with Poetry 1.1.2.

@gitpushdashf looks like this is an issue with the version of pip installed with your 3.7 installation. Looks like you are installing without a virtual environment. If this is the case, first try after perorming /usr/local/bin/python -m pip install -U pip.

Command ['/usr/local/bin/python', '-m', 'pip', 'install', '--no-deps', '-U', '/builds/[redacted]'] errored with the following return code 2, and output: 

Another possibility is, if you are using an Ubuntu distro, the distutils version installed might be interfering with your install.

[gitpushdashf]

Thanks for replying!

This is using the python:3.7 and python3.8 Docker images which I believe are Debian based. With that image should I be doing python3 -m pip install or is pip3 install okay?

[abn]

@gitpushdashf fwiw; I cannot reproduce this in a container, any chance you can provide some steps to reproduce this? Typically the containers should have python pointing to the tag version and pip pointing to the corresponding pip version. The use of python3.7 -m pip is more done for safety and portability.

$ podman run --rm -i --entrypoint bash python:3.7 -c 'pip --version'
pip 20.2.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

[abn]

Also this indicates you are using the old build-system configuration in your dependency project.

    File "/tmp/pip-build-env-l4t_85ci/overlay/lib/python3.7/site-packages/poetry/masonry/api.py", line 1, in <module>
      from poetry.core.masonry.api import build_sdist

I would recommend you try moving to the standalone build backend.

[jonapich]

I am also getting this error and I can reproduce it.

https://github.com/jonapich/test-poetry-setuptools

Clone that repo, and try "poetry install" in the test-functools folder, you will get the same stacktrace as in the bug report.

This seems pretty serious 🤔

I'm on 1.1.3, Windows, using powershell. I installed using the get-poetry bootstrap.

I have confirmed that this bug appears when going from 1.0.10 -> 1.1 and it was also working in 1.0.9

Also, I never used python 3.7; only 3.6 and 3.8.

[guhcampos]

I can confirm this is a problem and affects anything that ultimately still depends on calling python setup.py, such as:

• installing a poetry powered package with pip install -e
• using a local package in pyproject.toml like @jonapich demonstrates with test-testing = { path = "../test-testing/" }

I can confirm the problem with Python 3.6, 3.7 and 3.8 alike.

And this is really hard to debug because even if you literally copy and paste the command it's trying to run, it just works, in my case for a sample package:

[EnvCommandError]

To make this "work" I had to install bogus setup.py files to my packages, such as:

from setuptools import setup
setup(name="packb")

Yet it still fails when running from within poetry.

@jonapich based on your description I have attempted to recreate the scenario (minus the windows environment). Let me know what needs to be changed to reproduce the issue.

[jonapich]

I was able to make it work on a clean windows 2019 server as well... 🤔 But you need py3.8 or below, because there's no wheels for typed_ast in 3.9 and you'll need to install the vs c++ build tools.

I'll have to investigate what's different on my system.

[jonapich]

So far, I can still reproduce the issue when going through poetry, but not when going through pip. My issue matches the OP's behavior:

I went through the trouble of removing everything python and poetry off my system. I then reinstalled py3.8 using the latest installer and then reinstalled poetry using the Invoke-Webrequest method from the docs.

The behavior is still the same. Some observations:

• Through poetry run python -m pip list I can see setuptools is installed in the project's virtual environment.
• If I launch poetry run python I can import distutils.util

This is where poetry breaks it for me even though python/pip can handle it:

• If I launch poetry shell and then proceed to pip install ../test-testing/ it will fail.
• If I create my own environment python -m venv virtualenv and then call virtualenv/Scripts/pip install ../test-testing/ it works.

Additional note: The dependencies in test-testing have no effect on the issue. I tried to remove them all but I'm still unable to install it if poetry is involved with it.

I wasn't able to find the cause of the problem. After a fresh install of Windows 10, I am no longer experiencing the issue and I can install the test repo that I created for this issue.

Did something change between 1.1.3 and 1.1.4 that may have fixed this?

The repo reproduced the issue on my system only. Then I had to reformat for a non related reason, and I could not reproduce the issue anymore.

Sorry I cannot be of any more help. This issue is resolved as far as I'm concerned. Is your original issue still happening? Did you try to repo in a container or VM?
