Radian 0.6.9 fails to run on python 3.12.1

[alex-gable]

Environment

It looks like this is coming from a package dependency rchitect.

I know environments/versions can be finicky, but I tried to make this as clear-cut as possible (at least in my set up)

I use pyenv (to manage python versions) as well as pipx (to manage python CLI tools). So, in my .zshrc I first set PIPX_DEFAULT_PYTHON = "$HOME/.pyenv/shims/python". I then source ~/.zshrc to ensure my terminal environment is up-to-date.

Reproducing

From there I run pyenv global 3.12. after this, python --version returns 3.12.1. After this I install radian with pipx and attempt to run radian

radian installed with 3.12

> pipx install radian
installed package radian 0.6.9, installed using Python 3.12.1
These apps are now globally available

clearing the installed version of radian

then we need to make sure we clear the currently installed version of radian. to uninstall:

> pipx uninstall radian
uninstalled radian! ✨ 🌟 ✨

radian installed with 3.11

then we need to tell pyenv to use version 3.11 as the default:

pyenv global 3.11

I then exit the terminal and open a clean, new session. In that new terminal, I install radian again and confirm it was built with 3.11

> pipx install radian
installed package radian 0.6.9, installed using Python 3.11.7
These apps are now globally available
  - radian
done! ✨ 🌟 ✨

This log confirms radian was built with python version 3.11(.7). I then run radian.

> radian
R version 4.2.2 (2022-10-31) -- "Innocent and Trusting"
Platform: aarch64-apple-darwin20 (64-bit)

r$>

radian is now running as expected. please let me know if I can provide additional, clarifying information to help reproduce!

Hi Alex, thanks for your issue (and your workaround! ), I get a very similar error under windows 10 and python 12.1.
ModuleNotFoundError: No module named 'pkg_resources'

Some log messages below.

workaround for windows 10

• deinstall radian for python 312 (follow alex's example above)
• install Python 3.11 :)
• install radian again, for python 3.11
• add path_to_R_directory into windows PATH environment variable . In my system, i added D:\desktop\R\R-4.2.2\bin\x64 (Adapt as necessary).
• Make sure no variable named R_HOME is declared within those Windows environment variables: I had an Exception: Cannot load shared library: because of it.
• success !

log messages under python 3.12

[randy3k]

Please upgrade rchitect to v0.4.4.

[10b14224cc]

Please upgrade rchitect to v0.4.4.

I have rchitect 0.4.4, same error

Please specify in the README that python must be < 3.12

[randy3k]

Oh, python 3.12 no longer ships with pkg_resources by default. Please install it manually.

[alex-gable]

@randy3k should it be added as a dependency then so it installs by default?

[alex-gable]

Okay so, checking the notes for the changes that removed pkg_resources from python 3.12 it appears for those using pipx like myself the command that needs to now be run (until setuptools is added as a dependency) is:

pipx install radian --preinstall setuptools

for other users installing radian into a venv they recommend running pip install setuptools ahead of installing an application like radian.
