Pyramid packaging

[Thierry Florac]

Hi,

Sorry if this is not a real Pyramid topic, but I'm looking for a few advices...

I'm using zc.buildout for a very long time, with zc.recipe.egg, to build all my Python packages and also to handle all my deployment environments, and I've always been very happy with it!  :)

But since a few days, I can't install zc.recipe.egg with any Python 3.6 or higher version, only with Python 3.5! Here is a traceback from a Gitlab-CI job with Python 3.7:

52$ ./bin/buildout

113ValueError: not enough values to unpack (expected 1, got 0)

I have tried many things, but I actually can't make this work anymore!

So I'd like to find a solution for this problem, but if I can't, my question is just: what is actually a "good" way to handle building and deployment of Python packages, in a controlled and "reproducible" manner, for development as for production environments (for packages from Python 3.5 to 3.9)?

Very best regards for any advice!

Thierry

pip 21.0 was released on 2021-01-23. It dropped support for Python 3.5.

https://pip.pypa.io/en/latest/news/#id2

Perhaps try pinning pip to <21.0?

You could also stop supporting Python 3.5, which was EOLed as of 2020-09-13.

Hi Steve,

I know that Python 3.5 is outdated, but I still have old production environments which can't be upgraded before several months...

Anyway, I tried to create another Gitlab-CI configuration with Python support starting from release 3.7, with installation of zc.recipe.egg from pip instead of zc.buildout§ That works are start, but is failing afterwards on installation of "pyramid_chameleon":

53$ pip --version

Well...

It seems that the last release of zc.buildout is not compatible with the last setuptools release!

I downgraded setuptools to 50.3.2 and everything seems OK...

Anyway, my initial question is still open: what packaging and deployment tools do you use to have a full and easy control of a package and all its dependencies?

Best regards,

Thierry

I’ve been using pip-tools on my projects. I know several others who enjoy poetry.

Could you report this on the buildout issue tracker?

Thank you!

zc.buildout 3.0a2 should be compatible with modern setuptools. This is because 3.0a1 began using `pip install` instead of calling `setuptools.easy_install`.

FWIW, Based on the stacktrace, I do not think this is the cause -- but it could be. There have been a few related bugs in setuptools and pip regarding the version parser and tag_build directives; the errors I've seen were not like this - but I saw 3 completely different errors from these over the past 2 weeks:
