Can't launch Django server

I've started the Django tutorial and I'm at the step where I'm trying to launch the Django server (https://www.jetbrains.com/help/pycharm/creating-and-running-your-first-django-project.html?search=django%20tutorial#d58422e319).  When I type option-R, I see a window named "manage.py@mysite" and there appears to be a console window containing a prompt with the same label.  But I'm not seeing the development server starting nor the link to the "It Worked" page.  What am I doing wrong?  I've followed all of the instructions thus far to the letter.
