Hello dietdrpepper. Before I tell you about what I did and about my problems, I would like to apologize for the amount of doubt I have been having and at the same time try to thank you for your attention.
About my problems, I managed to solve them all and created a personal manual for when I need it again.
One of my problems was with the version of Babel that needs to be above 7.0, some Python dependencies needed for psycopg2, among others …
At the moment, I have one more question, but I think it is better to end this topic and create another one, because it is another matter.
Thank you one more time!
