Morse is not working on Python 3.7 #805

Closed dreuter closed 5 years ago

dreuter commented 5 years ago

Morse is not working on Python 3.7 due to async being a keyword since 3.7.

To reproduce this set Python 3.7 as your system python and run the minimal example from the tutorials.

morse create my_first_sim
morse run my_first_sim
$ morse run my_first_sim/
/usr/bin/morse:339: DeprecationWarning: The SafeConfigParser class has been renamed to ConfigParser in Python 3.2. This alias will be removed in future versions. Use ConfigParser directly instead.
  config = configparser.SafeConfigParser()
* Adding </home/dreuter/dev/my_first_sim> to PYTHONPATH and MORSE_RESOURCE_PATH.
* Using default scene in environment <my_first_sim/>.
* morse 1.4-165-gf9c8-dirty
* Version 2.79.0 of Blender is untested but should work

I do have a patch for this, but unfortunately this would mean changing the interface of a couple of functions.
