Running this command:

Resulted in this error:

Traceback (most recent call last):
File "<string>", line 1, in <module>
from reviewboard.wsgi import application; print('Success')

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

File "/var/www/reviewboard/venv/lib/python3.13/site-packages/reviewboard/wsgi.py", line 21, in <module>
raise RuntimeError(

...<2 lines>...

)

RuntimeError: The REVIEWBOARD_SITEDIR environment variable must be set to the Review Board site directory.

Setting this export REVIEWBOARD_SITEDIR='/var/www/reviewboard' results in a Success.
So for now I've added the following line in my apache config:

SetEnv REVIEWBOARD_SITEDIR /var/www/reviewboard
After restarting the apache server it first looked good, so I made a backup of the log to have a clean one, but the same fault.
After running the command /var/www/reviewboard/venv/bin/python -c "from reviewboard.wsgi import application; print('Success')" in de Reviewboard venv again the error log changed somewhat
Now it ends with:

RuntimeError: populate() isn't reentrant

I've run a basic python script in the revieboard venv that uses import and that runs okay.
So it looks like python is working normally in the reviewboard venv

Correction:

- Python version 3.13.5

This is fixed in git and will ship in 7.0.5 very soon.

Fixed in release-7.1.x (69504af). Thanks!
