wheel building fails #7042

Closed flynn1973 closed 2 years ago

flynn1973 commented 2 years ago 
      Python: 3.6.12
      platform: Linux-3.10.0-1160.49.1.el7.ppc64le-ppc64le-with-redhat-7.9-Maipo
      pip: n/a
      setuptools: 59.6.0
      setuptools_rust: 1.1.2

as no ppc64le binary is availabe (yeah, who cares about this "esoteric" platform), i was forced to build it myself, alas it fails.

/var/lib/awx/venv/aix-custom-venv/bin/pip install cryptography --no-binary cryptography

2022-04-05T16:11:12,437     Link requires a different Python (3.6.12 not in: '>=3.7'): https://files.pythonhosted.org/packages/4f/27/b51cc9cebfd53b168b8a187c844e7a67dc523dda76be9b46d532815df284/setuptools-59.7.0-py3-none-any.whl#sha256=0c8d5c36aea600828875ab751c03e2c52624edc8382a88a127e31bd8d860e34b (from https://pypi.org/simple/setuptools/) (requires-python:>=3.7)

point is, i have python 3.6.12 and switching to 3.7 is not possible. so how to get this going?

reaperhulk commented 2 years ago

The error messages provided don't provide enough context here unfortunately. It does appear that cffi is failing to properly install, which is a dependency cryptography needs both at build and runtime. I'm not sure where the >=3.7 is coming from though. We test 3.6 and all our deps in CI, albeit not on ppc64le, but that shouldn't be a factor for Python version support.

tiran commented 2 years ago

It's coming from setuptools installation attempt. 59.7 requires Python >= 3.7.

alex commented 2 years ago

Which merely changes the question to "why is pip trying to user that version"?

What version of pip is /var/lib/awx/venv/aix-custom-venv/bin/pip

flynn1973 commented 2 years ago

pip version in venv:

(aix-custom-venv) root@lpgaixmgmtlx01:/var/lib/awx/venv/aix-custom-venv>pip -V
pip 21.3.1 from /var/lib/awx/venv/aix-custom-venv/lib/python3.6/site-packages/pip (python 3.6)
flynn1973 commented 2 years ago

cffi is installed in venv:

To me this looks like somehow your CFFI installation is broken. My suggestion would be to clear out your wheel cache, which I suspect contains a corrupted cffi wheel or something like that.

no wheels in cache...

problem with your script:

python3 -m venv cryptography-venv
pip3 install --upgrade pip
pip3 install --editable .

pip3 install --requirement dev-requirements.txt
python3 ./setup.py build
python3 ./setup.py bdist_wheel

You create the venv, but never active it, so the pip3 invocations are all using your global pip, not the venv one.

flynn1973 commented 2 years ago

already fixed the script, the build error remains....

reaperhulk commented 2 years ago

There are multiple build errors here, _cffi_backend and setuptools_rust . For the latter there is something wrong/outdated in your environment that's causing pip not to properly process the install dependency from pyproject.toml on setuptools-rust. This can be manually worked around by simply installing it directly (pip install setuptools-rust in the venv). For the cffi error despite it appearing installed in the environment the native module is missing, which means it did not successfully install. You'll need to figure that issue out.

flynn1973 commented 2 years ago

the setuptools-rust problem is fixed by forcing installation in the venv...

concerning the cffi native thing...its already in the venv too.

Does it work with other cffi projects like bcrypt or argon2-cffi? The import failure shown in the error suggests that a temporary installation pip is doing in a pep517 environment is failing…

flynn1973 commented 2 years ago

ahhh, good point....does not work with bcrypt and others, something is really borked with that cffi stuff. no idea how to proceed from here...

alex commented 2 years ago

Are you able to provide a dockerfile or similar reproducer from a clean image that demonstrates the issue? Right now none of us know how to reproduce this issue.

flynn1973 commented 2 years ago

this is on a fat physical machine, i dont dont think its possible to provide a container file. seems to be a somewhat isolated problem anyway, so i will close this....
