Install fails on mac

#1 by EvgenyK

I am having issues installing oTree on Mac Monterey. After installing Python and oTree I get the following message: 

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/otree", line 8, in <module>
    sys.exit(execute_from_command_line())
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/otree/main.py", line 106, in execute_from_command_line
    setup()

What command did you run to get this message? "otree devserver"? Anyway, check your settings.py; it seems it is missing the required SESSION_CONFIGS setting.

Thanks Chris.  This seems to be an issue with PyCharm/creating a virtual environment.  When I open an old project on my new machine using PyCharm, the folders all show up as empty.  I think the only way around this would be to create an entirely new project and copy and paste the folders.
