it's possible there was never a virtualenv involved... on a Linux system
you'd normally install the distribution package for django, instead of
installing bits in a virtualenv. The distro package contains a template
manage.py. Which, on a current Fedora, contains wording suggesting maybe
a virtualenv wasn't started - but the real message is that it couldn't
find necessary Django pieces in the python environment (this is
consistent with your original message, suggesting it found and is
running manage, but other things are missing).

Here's the interesting part of the content of that template for those
who might have more ideas:


if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "{{ project_name
}}.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)
