What should I do?

Answer 1

Permission denied error is usually caused by incorrect owner, group, or file mode setting of the file to be loaded or one of the subdirectories leading to it. Another possible cause is SELinux, but only if it is enabled and in enforcing mode.

Permission denied: '/root/.local/share/virtualenvs/movie_douban-og6kh8C1/bin/activate_this.py'

In this case, almost certainly the Apache process has no access to /root directory (ie admin's home directory), because it is running under UID of apache or httpd user.

You should move your virtualenv files to a more suitable location.
