Mediagoblin gmg error

[Eugene Kovalev]

Hello,

I am running into a problem with MediaGoblin. I followed the instructions for setting it up here: https://mediagoblin.readthedocs.io/en/master/siteadmin/deploying.html but when I get to the step "Update database data structures" and try to run gmg, I get the following error:

Traceback (most recent call last):

  File "./bin/gmg", line 33, in <module>

    sys.exit(load_entry_point('mediagoblin', 'console_scripts', 'gmg')())

  File "/srv/mediagoblin/mediagoblin/gmg_commands/__init__.py", line 109, in main_cli

    setup_func = import_component(command_struct['setup'])

    from mediagoblin.tools.metadata import compact_and_validate

    from jsonschema.compat import str_types

ModuleNotFoundError: No module named 'jsonschema.compat'

I seems like the jsonschema module is not available, however, `pip3 install jsonschema --user` did not fix this. I was wondering if this was a known problem and if there was some kind of fix.

Thank you!

Sincerely,

-Eugene
