@Dei6 Heya! Please follow these steps

I’d recommend to create a fresh conda environment with python 3.7 or 3.8 and follow the step

`pip install rasa==2.8.1`
`pip install rasa-sdk==2.8.1'

check version rasa --version its install or not

then

pip install rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple

check rasa version rasa --version its install or not

You will see some error : ImportError: cannot import name ‘RowProxy’ from ‘sqlalchemy.engine’ Install

pip install SQLAlchemy==1.3.22 should fix it

If sanic related error: pip install sanic-jwt==1.6.0

delete .db if is showing alembic issue.

Good luck! I hope this will solve your issue. If you have any doubts please asked ok? I hope you created the environment??

I use pipenv environment with python 3.7。
Is it necessary to use conda environment?

4

@Dei6 Well, honestly I never used the pip environment, but it recommended by rasa to create the environment (I guess conda based environment) so please try the above mention steps and let us know.

The error described is attributable to Windows Python using (accidentally) the wrong encoding when reading the YAML files and pushing into the rasa oss API.

Set the environment variable PYTHONUTF=1 before starting rasa x to frace Python to use UTF8 even if it is not platform standard!

I encountered this issue as well. And my solution is just delete some incorrect parts in stories_yaml.
