Could not build wheels for pendulum which use PEP 517

[weskerfoot]

• I am on the latest Pendulum version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• Alpine 3.11 in Docker

• Pendulum 2.1.0

Issue

I get an error about PEP 517 when trying to install Pendulum. The following Dockerfile (run with docker build .) reproduces the issue.

The error is ERROR: Could not build wheels for pendulum which use PEP 517 and cannot be installed directly

FROM python:3.7-alpine3.11
RUN apk update \
    && apk add gcc musl-dev python3-dev py3-setuptools libffi libffi-dev openssl-dev \
    && pip3 install pendulum==2.1.0

[altendky]

My quick looking suggests...

1. It's Alpine so the pendulum wheels aren't used so that explains the issue not being as wide spread as it might be
2. The poetry tarball doesn't list setuptools as an install_requires and thus the isolated build env doesn't have setuptools (the poetry .whl should be used but I know where to look in the tarball...)

Now I'm not sure of the nuances here and I haven't tested my theory quite yet but... FWIW.

[weskerfoot]

Workaround (for this situation, running in Docker with Alpine)

FROM python:3.7-alpine3.11
RUN apk update \
    && apk add gcc musl-dev python3-dev py3-setuptools libffi libffi-dev openssl-dev \
    && pip3 install poetry \
    && pip3 install --no-build-isolation pendulum==2.1.0

[aniljaiswal]

Any workarounds for people using pipenv? I'm using the same docker setup but using pipenv and lock files.

[Hellowlol]

I'm having the same issue in the home assistant 107.7 (hassio)

[weskerfoot]

Any workarounds for people using pipenv? I'm using the same docker setup but using pipenv and lock files.

Does pipenv have a similar option to disable build isolation? That would most likely work, though I'm not really familiar with how pipenv does things.

[altendky]

Poetry would be building it I would think. But, pyproject.toml will get hit first (for 517-compatible pips) and that specifies poetry as the build backend not setuptools. And poetry is missing an install_requires for setuptools afaict thus causing the error. So it seems to me that either that needs to be addressed or pendulum needs to build a pyproject.toml with a build-system requires including setuptools and the corresponding build-backend.

[altendky]

@davegallant, commit-wise it looks to be: python-poetry/poetry@f759876

[altendky]

I just realized we don't have a full log here. @weskerfoot, could you add that?

[weskerfoot]

@altendky done
docker_build.log

[aniljaiswal]

Any update on the above issue?

[altendky]

I think python-poetry/poetry-core#24 (also mentioned at https://github.com/python-poetry/poetry/pull/2262/files/ad2c8d80f4f04a95769a5955e4367f1351aaca76#diff-d4e7f533c342aecaeb13b29ca6c1bf24) should resolve this. I have not tested at all, just getting the cross-references added.

Thanks @abn.

[nathan5280]

I was able to get this to work in my dockerfile by downgrading my version of pip. I didn't keep track of all the details, but it seems that up to about version 1.0.4 it works with pip 19.x. After that we get the issue listed above.

pip install pip==18.1

[ThanhTuNguyen]

Please fix this issue, thanks

Why is poetry required to install pendulum?

[altendky]

Poetry is required to build pendulum. If you are on a system for which wheels (prebuilt packages) are not provided then it needs to be built from the source distribution. This can also happen if you tell pip not to use wheels. If you can and do use the wheels then poetry should not be required.

[enercalc]

Windows: Install (python -m pip install pendulum) works on pip 18.1, doesnt work on pip 19.2.3.

Wasn't clear if you folks had the log you needed, so...

Can confirm that I get the same error @enercalc is getting.

• Windows 7 Build 7601
• Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 22:45:29) [MSC v.1916 32 bit (Intel)]
• setuptools 47.1.0

Pendulum 2.0.3 installs correctly.

[ghost]

Windows 10 :

I installed the PIP version 18.1 with the below command
C:>pip install pip==18.1

Then Install the pendulum with the command:
C:>pip install pendulum

No errors now

[weskerfoot]

Poetry is required to build pendulum. If you are on a system for which wheels (prebuilt packages) are not provided then it needs to be built from the source distribution. This can also happen if you tell pip not to use wheels. If you can and do use the wheels then poetry should not be required.

To add to that, the reason it's an issue on Alpine is because Alpine doesn't have prebuilt wheels available (because it's using musl libc, so it needs to get recompiled for that), so you have to build them from source every time you install it.

We build wheels for Alpine and serve them via devpi so we don't have to have build tools in containers and such. And we still have problems building a wheel for Pendulum :)

[ThanhTuNguyen]

Someone should fix this bug, it's been a couple months. i can not downgrade my pip, it will effect to other libraries. Right now i just mess up to my docker file in order to install poetry and pendulum directly into container. Its a bizarre solution :(

[joshourisman]

For pipenv users, this got my Pipfile with a pendulum dependency installing on Alpine:

FROM python:3.8-alpine

RUN apk update \
    && apk add --no-cache build-base postgresql-dev openssl-dev libffi-dev \
    && pip3 install -U pipenv poetry

WORKDIR /app
ENV WORKON_HOME /app/.venvs
COPY Pipfile Pipfile.lock ./
RUN pipenv install --deploy --site-packages

The important parts are installing poetry with the system pip, and then adding the --site-packages flag when invoking pipenv install.

[frostming]

There are multiple reasons behind this:

1. Alpine can't match any of the wheels released on pypi
2. Building pendulum from source dist requires setuptools, but it is not specified in pyproject.toml's [build-systems] requires
3. Starting from pip 19, it creates a clean isolated environment to install PEP 517 powered libraries.

So the corresponding resolution will be:

1. If possible, use slim images instead of alpine
2. Downgrade pip to 18.1
3. Otherwise, use the following commands to install:

   $ pip install poetry && pip install --no-build-isolation pendulum

4. Waiting for @sdispater to release a new version of pendulum with fixed pyproject.toml

[williamjacksn]

I got tired of this so I built my own Python package index with wheels for Alpine Linux.

[RazerM]

I really like pendulum, it's baffling that this hasn't been resolved for so long. I understand that the author wrote poetry but it's not a glowing endorsement that people haven't been able to install pendulum for three months because of it.

I was able to solve it in Windows 7, Python 3.8 32 bits following @frostming advice, above.

[sdispater]

This should be fixed in the latest 2.1.2 release.

[ThanhTuNguyen]

It work like normal. Just tested .Thanks

i am getting the same error while installing mysqlclient

DEPRECATION: Could not build wheels for mysqlclient which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above.

wheel issue is-

[altendky]

@ritumishra9, I would suggest reporting this to mysqlclient. Though the references to mysql 0.0.1 and client 0.0.2 seem odd.

I'm still supporting people (with more or less success) that are getting this exact same issue at the end of 2021. 👎

[altendky]

It usually works best to create a new ticket with complete details of your case and a link to the existing ticket that you think is related. It's hard to help when the issue appears to be solved and no new information is provided.

To be clear, I'm not particularly involved with this project. Just offering some guidance on a path forward that's more likely to result in fixing your issues.

[spacemanspiff2007]

It usually works best to create a new ticket with complete details of your case

It's difficult because I use pendulum as a dependency for an application and the users try to get support from me and often don't provide all the required information.
That would be much appreciated since I am far from an expert! I just try to get them to do things that I found in the issues here.
So far it seems that pendulum 2.1.0 will install on most the machines without issues.

Ideally we would consolidate these infos e.g. pendulum requires poetry or otherwise it won't install properly with pip.

[altendky]

The new issue bug report template provides a starting point. Generally speaking you want the OS including version and architecture, Python version, Pendulum version, full terminal session (prompt, command, and output), and maybe also other cases where the same thing does work to help isolate what differences might show the issue. If the command you are running has a verbose option the full output as above could also be provided with the extra verbosity.

Note: This error originates from the build backend, and is likely not a problem with poetry but with pendulum (2.1.2) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pendulum (==2.1.2)"'.

I'm also getting errors on attempting to install Pendulum, with nominal "pendulum (2.1.2) not supporting PEP 517 builds".

[edgarrmondragon]

@ethanmsl Pendulum 3.0.0b1 has wheels for M1 macs and Python 3.12, but builds of Pendulum 2.* on Python 3.12+ seem like they'll be forever broken.

[zakkg3]

Still....

This error originates from the build backend, and is likely not a problem with poetry but with pendulum (3.0.0) not supporting PEP 517 builds.

[Secrus]

You didn't post any logs, so I am guessing blindly.
To build Pendulum 3.0 from source, you need rust compiler installed on the machine (or in this case in the container)
