Problem with Configure

[omar-karray]

in the setup phase of Eurorack-blocks I'm on Mac 13.0.1 (22A400) Apple M1 Pro, i have installed python brew install python then erbb setup on the cloned folder all the steps right :) where I execute erbb configure on the drop folder I get this problem.

Found the Issue Dependency conflict between the install phyton3.11 on Mac and the installed one by brew.

Hi @omar-karray yes it's what it looks like.

The python installed by homebrew is configured to read into /opt/homebrew/lib to find libraries, and here your installation of python is a different one, so it can't find the libcairo.2.dyliblibrary.

Please try the following as a workaround:

DYLD_LIBRARY_PATH=/opt/homebrew/lib erbb configure

Does it work?

[ohmtech-rdi]

Ah sorry, I've read too quickly.

Could you please tell how you made to select the right version of python? I think some other people would be glad to know.

[omar-karray]

hey @ohmtech-rdi Thank you for your reactivity. the process is easy remove all the python library sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.11

then remove the app from the application folder

sudo rm -rf “/Applications/Python 3.11"

then break that simlink that make the hole trouble :)

ls -l /usr/local/bin | grep ‘../Library/Frameworks/Python.framework/Versions/3.11’

after that make sure that python3 is installed via home-brew

brew info python3
if not installed

brew install python3

and you are good to go. finally will it be more interesting to have it dockerized with a docker image for erbb ? all the best Omar

[ohmtech-rdi]

Hey @omar-karray !

Ah ok, I was wondering if you were keeping multiple environments and were using some sort of pyenv to move from one to another.

Happy to know it works for you!

And about Docker, there was this issue about it. Since installation is the main pain point of Eurorack-blocks, if you have a good idea on how to achieve this, please feel free to experiment or implement this!

My current idea about it was to make a self-contained release, pretty much like how aws-cli is installed as far as I remember.
