Hello

I am trying to install daphne with PIP, which uses autobahn. So, when I am trying to install autobahn (I am using Twisted==22.10.0) with the following command: pip install autobahn[twisted] I get the following error:

  note: This error originates from a subprocess, and is likely not a problem with pip.

hint: See above for output from the failure.

I am running this inside a virtual env with pip 23.0, on an Ubuntu 20.04.5 LTS machine. Let me know if you need more info.

no idea, works in the CI with older python and current twisted

https://github.com/crossbario/autobahn-python/actions/runs/3925457332

but your setuptools might be too old (for the plugin system of your twisted version, which is what triggers this I guess)

IOW: you could try pip install -U setuptools and then pip install twisted - or directly pip install autobahn[twisted]
