Running Plone 5.2.5 unified installer on macOS 12

Development Installer
1

I'm going to start a thread as I try to get 5.2.5 building on macOS 12 (beta, yeah yeah I know... long story)

As per the instructions at 6. Installation & Setup of Plone 6 – Mastering Plone 6 Development — Plone Training 2021 documentation

brew install zlib git readline jpeg libpng libyaml

was not quite sufficient. I had to do this too:

export CPPFLAGS="-I/opt/homebrew/opt/jpeg/include/"
export LDFLAGS="-L/opt/homebrew/opt/jpeg/lib"
export CPPFLAGS="$CPPFLAGS -I/opt/homebrew/opt/zlib/include"
export LDFLAGS="$LDFLAGS -L/opt/homebrew/opt/zlib/lib"

Then be sure to specify Python 3.x (as per the training installations, I used pyenv and activated a Python 3.9.9 virtualenv already):

./install.sh --with-python=`which python` standalone

Holy **** Plone starts quickly on M1 Macs :slight_smile:

Yes, it's somewhere between 1.5-2.0 times faster when you compare it to the previous rather fast Intel systems Apple built.

Then be sure to specify Python 3.x (as per the training installations, I used pyenv and activated a Python 3.9.9 virtualenv already):

YMMV with pyenv. I have also seen that there were sometimes system library dependencies missing for python add'ons like Pillow that you first have to install with brew and then pass on/reference using LDFLAGS and CFLAGS.

But 'CAVEAT', my carefully selected LDFLAGS/CFLAGS set I created last year to get python3 and even python2 working on M1 macs has also been the cause of all my envs slowly breaking down after I upgraded to Monterey last month. It first seemed to work, but I got mysterious setuptools/pip errors when python packages need to be rebuilt.

I'm now almost at a state where I repeatable see what is going on and will write something more extensive here on community later, but a pyenv installed python can break when Xcode/CommandlLineTools/brew packages are updated.

A homebrew provided Python has the advantage that is already linked against the same other (Home)brew supplied packages.The big drawback is that brew only supports Python because it is a dependency of many other brew packages/software. So the brew maintainers can and will just remove a python minor version or replace it with a newer patch version when they think it is appropriate.

I wonder how pyenv compares to conda for repeatable envs. I don't come across a lot of devs, outside of data science, that use conda but it has worked for me.

I followed those instructions to install Plone 5.2.9 on my macOS 12.6 Intel Macmini but I got these 'ValueError: not enough values to unpack (expected 1, got 0)' error.

Does anyone know how to solve this issue?

An error occurred when trying to install /Applications/Plone529/buildout-cache/downloads/dist/zc.recipe.egg-2.0.7.tar.gz. Look above this message for any errors that were output by easy_install.

Try with Python 3.8. Plone 5.2 does not support Python 3.9.

Post the full log, the problem is in compiling Zope I think.

If you search for that error message on this forum, you will find other posts that indicate old versions of the build tools, e.g.,

Ah..I see. I've overlooked supported python version. I'll try with python3.8.
Thank you.

Hi, I've already checked that post, too.
Thank you.
