installation fails (relies on 'formatargspec' which was removed after python3.10)

[BMaxV]

Hi everyone,

the install instructions don't work for me, I'm on Ubuntu 24.04 and that's using python3.12

The first problem was the cairo version, which I solved by trying the installation in a venv, which worked, but now I'm running into an error that ends like this:

...
File "/tmp/pip-install-l7u3d3ai/wrapt_6be4374b6f7f4b05b02ded7eb9a43786/src/wrapt/__init__.py", line 10, in <module>
          from .decorators import (adapter_factory, AdapterFactory, decorator,

          from inspect import ismethod, isclass, formatargspec
      ImportError: cannot import name 'formatargspec' from 'inspect' (/usr/lib/python3.12/inspect.py). Did you mean: 'formatargvalues'?
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

And that seems to be a problem because "formatargspec" was deprecated in 3.5 and removed after python3.10

python/cpython#89483

I would have loved to check out the project, maybe this can be updated?

if I missed something else, please let me know.

Thanks!

Thanks for posting the issue and finding this incompatibility. Right now we are still using python 3.9 and thus didn't come across this yet. We will take a look!

For now, maybe you can just create a venv with python 3.10 or lower?

[JohannesErnst]

This should be fixed in 6f2ff84, although I cannot thoroughly test it right now as I am lacking access to an Ubuntu System with python 3.12.

The update will be deployed with the new minor version 2.2.0 within the next days.

[JohannesErnst]

We released the new version 2.2.0: https://github.com/DLR-RM/RAFCON/releases/tag/2.2.0

Could you @BMaxV please check if it works now via pip with your setup?

Hi,

I can confirm that the original problem was resolved, however trying to install and run it, I was also encountering this:

../meson.build:31:9: ERROR: Dependency 'gobject-introspection-1.0' is required but not found.

which was fixed by installing libgirepository1.0-dev because I'm on ubuntu

After that the build and install appeared to work? There were no install / build errors anymore.

Now launching:

I had to install setuptools with pip which was not an issue.

Then I'm running into this:

Is this enough error log, or do you need more?

Thanks for the quick fix! A week is amazing!

Hi, thanks for the update. I am sorry that the changes didn't fully fix the installation problem. Unfortunately, we are currently lacking the resources to test the installation with the mentioned system specifications.

I hope that we will, in the future, be able to provide a stable release for ubuntu and latest python versions. In the meantime, if you happen to figure out a way to install and launch it, hopefully you can post some update here. Maybe the solution with a virtual environment for e.g. python 3.9 works...

[BMaxV]

Alright, thank you very much for your effort, I think I will just close it then. The original problem was fixed after all.
