Hi,
I am new to rasa. I have just to install rasa-x using :
$ pip install rasa-x --extra-index-url https://pypi.rasa.com/simple
and all right 
But i tried to start run in de docker rasa with versión tags (1.1.4-full) and (latest-full) and result is:
======================================================================= root@803f6b96d415:/app# rasa x --debug
2019-07-01 15:57:42 DEBUG pykwalify.compat - Using yaml library: /usr/local/lib/python3.6/site-packages/ruamel/yaml/init.py
2019-07-01 15:57:42 DEBUG rasa.cli.utils - Parameter ‘endpoints’ not set. Using default location ‘endpoints.yml’ instead.
Rasa X currently only supports a SQLite tracker store with path ‘tracker.db’ when running locally. You can deploy Rasa X with Docker (https://rasa.com/docs/rasa-x/deploy/) if you want to use other tracker store configurations.
? Do you want to continue with the default SQLite tracker store? Yes
Starting Rasa X in local mode…

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up. If you need help fixing the issue visit our forum: http://forum.rasa.com/.
Hope you can help me out! Rasa X seems great! I’m really eager to give it a try
