During handling of the above exception, another exception occurred:

Traceback (most recent call last): File “/usr/local/bin/rasa”, line 8, in sys.exit(main()) File “/usr/local/lib/python3.6/dist-packages/rasa/main.py”, line 92, in main cmdline_arguments.func(cmdline_arguments) File “/usr/local/lib/python3.6/dist-packages/rasa/cli/x.py”, line 326, in rasa_x run_locally(args) File “/usr/local/lib/python3.6/dist-packages/rasa/cli/x.py”, line 434, in run_locally print(traceback.format_exc()) UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\U0001f680’ in position 361: ordinal not in range(128)

That’s the codepoint for the rocket emoji. I think the codec you’re using for your development environment is ASCII only so can’t handle printing non-ASCII characters. I don’t think it should affect Rasa X actually launching, but there are some troubleshooting tips in this SO question.
