Trying to install Apache Superset "from Scratch" according to official instructions: "https://superset.apache.org/docs/installation/installing-superset-from-scratch/" on Ubuntu 22.04 OS:
Оn first step, "OS Dependencies", Python3.10 was installed.
- "Then, you need to initialize the database: superset db upgrade"
- this command had many errors, but, after execution: a) "pip install sqlparse=='0.4.3'" (advice from "https://github.com/apache/superset/issues/23742") b) "export FLASK_APP=superset" (reference to this variable was required in error message) db was upgraded without errors.
- "# Build javascript assets cd superset-frontend npm ci npm run build cd .. "
- directory "superset-frontend" does not exist in the whole system as well as no such record in pip or apt repositories (and I do not see any errors in command execution prints on previous steps).
I do not know what I can do in this case (afraid all that are "by design")... Can somebody help? Is it possible to install Apache Superset "from Scratch" on Ubuntu 22.04? What exact sequence of commands needed for that?
