I'm using zc.buildout (with zc.recipe.egg) since a long time to build my Python packages and deploy my running environments.
Since a few days, I can't use it anymore with any Python version higher to 3.5! :(
On startup, I receive an error (here in a Gitlab-CI job):
$ pip install zc.buildout

I actually use the last setuptools version (52.0.0), and I need to be able to build my packages for all Python versions from 3.5 to 3.9...
Any idea?
Best regards,
Thierry
I encountered the same problem and believe I have found the underlying problem.
The latest setuptools version (52.0.0) removed easy_install which is used by zc.buildout.
See this PR for reference: https://github.com/pypa/setuptools/pull/2544
To solve (at least for now), you can explicitly install/require a previous version of setuptools.
