I don’t understand the reason for the error: Tue Jan 11 15:27:45 2022 – failed to open python file /root/eva/lawyer/lawyer/wsgi.py I can’t understand why uwsgi can’t open this python file. The path to it is right

Tell me, please, what could be the cause of the error and how to solve it? This seems like an easy problem to solve. But I couldn’t find information about it on the Internet

Answer
Check your file permissions for the Django project.You have your WSGI worker configured to use the account ‘www-data’. Either change this to an account that has access to the directories and file, or change the files permissions.
You can validate the file permissions by running ls -la in the directory. The third column shows the owner and the fourth column shows the group.

You can change file and folder permissions by running chown www-data:www-data ./* in the project directory.
I do not recommend keeping the files in your root directory, that should be protected. Instead consider moving them to /var/www or /var/app.
To validate if its a permissions issue, you could change your uWSGI configuration to make the uid and gid root, but do not use this in a production setting.
