Issue

Attempting to install poetry with the --no-binary flag like so:
pip install --no-binary=:all: poetry fails with the following error:

(The verbose output of the command is too noisy so has been elided. However, this should be reproducible with any system.)

pip install --no-binary=:all: poetry

However, installing clikit with the --no-binary=:all: flag results in an error installing poetry implying a cyclic build dependency.

Is there any plan to resolve this? We also build all of our packages from source, and this breaks our ability to build anything that depends on or uses Poetry as its builder.

[PaulNewtech]

Same problem for us

[ryansobol]

Just ran into this problem today. My use case is attempting to install a Python application—that uses Poetry as its build tool—via Homebrew. pypa/pip#8404

[preston-hf]

Anyone found a workaround?

[abn]

@preston-hf replacing the build-system section with the following will work. However, this requires every poetry project in your dependency graph to do the same, otherwise when pip attempts to build from source it tries to also build poetry from source which will fail because pastel in poetry's dependency graph is awaiting a fix (sdispater/pastel#8) that is exactly this issue. :)

[build-system]
requires = ["poetry-core>=1.0.0a9"]
build-backend = "poetry.core.masonry.api"

[ryansobol]

@abn Thanks for sharing this workaround! I took a look at the README for poetry-core. So the plan is to integrate it into poetry v1.1.0?

[abn]

@ryansobol yes. One of the main changes in 1.1.z is the decoupling of the PEP 517 build backend (poetry-core) and the poetry the tool.

[abn]

This should no longer be an issue. The current master branch works without any errors when using the --no-binary option. It is recommended that packages using poetry as a backend switch to the lighter and purpose built poetry-core instead.

Ouput from installing master branch.

$ pip install --no-binary=:all: --pre git+https://github.com/python-poetry/poetry.git@master

@abn - is there a timeline for releasing the next version of poetry to PyPI? I work on the Homebrew project and was thinking about submitting Issues/PRs to projects to have them use poetry-core instead so that source builds work and they can be updated/included in Homebrew, but a newer release of poetry would solve this problem "for free".

Also, the newest version of of poetry-core (1.0.0a9) has "a" in its name - presumably for alpha - and is marked as a pre-release on GitHub: https://github.com/python-poetry/poetry-core/releases/tag/1.0.0a9. Is it stable enough to be used in production?

We are trying for end of this month. But with all of us being busy elsewhere that might slip again :(

so that source builds work and they can be updated/included in Homebrew

I am curious as to why this is required since pip already takes care of building from source when required and platform dependent packages already have bot osx and manylinux binaries in a lot of cases, for the rest the PEP 517 builds should in theory take care of it.

but a newer release of poetry would solve this problem "for free".

Yes it does. However, remember that using poetry itself as a build backend is rather inefficient because of the dependencies it will pull in. Moving to poetry-core is still recommended. But yes, in a a sense things would just start working even if they use poetry, but there is no guarentee that somethign in the dependency graph would introduce another breakage later on.

Considerting the code is basically copy paste from 1.0.x, I think it is safe enough for now. But we do expect a new stable release to come out before poetry's next release.

[dtrodrigues]

Homebrew attempts to build from source in almost all cases in cases (https://docs.brew.sh/Acceptable-Formulae#we-dont-like-binary-formulae), so we need to compile the python dependencies from source vs depending on the pre-compiled wheels, and do so via (approximately) pip --no-binary :all:, which fails with the currently released poetry version: https://github.com/Homebrew/brew/blob/f04b0142102a872d255440aef75984c1b213c584/Library/Homebrew/language/python.rb#L293-L295

I definitely agree that it would be better if projects transitioned over to poetry-core, and I'm happy to suggest they do it, but I also don't have a great sense for how many projects that are directly/indirectly relying on poetry and how much work it would be on the Homebrew end and go through and individually request that projects update.
