Hi All

Issue is with the package version.
Got the same issue in python3.8
Fixed by
pip3 install Jinja2==2.10.1
pip3 install MarkupSafe==0.23

Hi All

could you please check the possibility

python install requirements.txt

May be a python site-packages problem.

Output:

Hi ,
Can you please check your addons path. I guess you missed to add the addons path.
Try with :

            python3 ./odoo-bin --addons=addons/

Please check the python version as per requirement.

Hope it will help you.
