Rasa X test core stories

when I run that commande rasa test core --stories test_stories.md --out results I received Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are using (Ana)Conda please install python.app and replace the use of ‘python’ with ‘pythonw’. See ‘Working with Matplotlib on OSX’ in the Matplotlib FAQ for more information. how can I solve that ? thank for adv

Looks like you might not have python installed?

I ran into this using a miniconda environment - for me it was solved by upgrading my version of matplotlib (to 3.1.2)
