Not possible to install backoff from source distribution about backoff HOT 15 CLOSED

Are there any plans to address this? My team as well as others at the company are pinning to 1.6.0 as our build process requires installing dependencies from source

from backoff.

I have pip at 20.0.1 and this still fails.

It makes not possible to use backoff as AWS Lambda dependency.

This is frustrating because the only way I'm sure how to fix this is to go back to setuptools. I can try to take another stab at finding a workaround.

@bgreen-litl
Don't let your fans down because of somebody else (poetry) problem.

from backoff.

Closing, as this seems to work fine now.

from backoff.

Ugh.

I followed a trail of comments and issues from python-poetry/poetry#760 and it sounds like the issue might possibly be fixed by a forthcoming version of pip? pypa/pip#5739

I also read that flit had a similar issue with circular build dependencies but ended up working around it even without an updated pip. I would rather try to stick to the PEP 517 route rather than convert back to setuptools if I can help it. That could mean either waiting for a pip or poetry update or maybe we could look into using flit if that is immune from this issue.

@bgreen-litl I tested with current pip from master and the problem still persists. pep 517 (as expected) doesn't solve the problem of circular dependencies within build dependencies.

I would rather see poetry being fixed, so maybe lets wait for a resolution from that discussion.

Maybe a quick resolution would be to generate setup.py using https://pypi.org/project/poetry-setup, as part of the release process. I never tried it, but I guess that should work.

Do you think this will work around your problem? #68

I simply ran poetry-setup and checked in the generated requirements.txt and setup.py

from backoff.

in short: Still doesn't work, but if remove pyproject.toml then it works.

Here is what is did to test:

1. install pip from master

% cd /tmp
% git clone https://github.com/pypa/pip
% cd pip
% virtualenv env
% ./env/bin/pip install -e .

2. Install backoff via url

% ./env/bin/pip install --no-binary :all: https://github.com/bgreen-litl/backoff/archive/e9a43c09d7155c8ad5e00af529c46450a08568d4.zip

3. Install backoff from path without pyproject.toml

% cd /tmp
% git clone https://github.com/bgreen-litl/backoff
% cd backoff
% git checkout poetry-setup
% rm pyproject.toml
% cd ../pip
% ./env/bin/pip install --no-binary :all: ../backoff

I'm still poking into this upsteam, but does pip install --no-use-pep517 . allow you to do the setup.py build without removing pyproject.toml?

from backoff.

@garbas Is there any flags I can pass to pypi2nix so that I can test the question above?

I'm itching to package up the latest Apache Airflow build for NixOS but I can't using pypi2nix until this is resolved.

from backoff.

Is there a plan to release a fix for this?

from backoff.

It appears that poetry might have a fix for this now?

python-poetry/poetry#760 (comment)

Would someone be willing to test this?

from backoff.

This seems fixed? I didn't do anything on the backoff side, but it seems this was fixed upstream...
