dagit: command not found

[tungndtt]

I followed the guide on the official webpage https://docs.dagster.io/getting-started. In order to get a web-based interface, i ran pip install dagit to install dagit and then dagit -f script.py.

However, in the terminal, it shows

dagit: command not found

Im using Window system and the error means that i need to add the DAGIT_HOME_DIR in the environment variable path. However, i couldn't find that directory. When i ran pip show dagit, the following information was displayed:

Went to the location, i just saw a python webserver application without any .exe files.

I'm not sure if i was missing something ? Would appreciate if some one can point it out !
