ImportError: CrewAI is not installed. (despite calling pip install "praisonai[crewai]")

[AgatheBauer]

I tried getting the PraisonAI framework to run multiple times with a clean installation into a venv:

rm -rf /praisonai
python3 -m venv /praisonai
source /praisonai/bin/activate
pip install "praisonai[crewai]"
pip install -U "praisonai[ui]"
export OPENAI_API_KEY="xxxxxxxxxxxxxxxxxxxxx"
export OPENAI_BASE_URL=https://api.groq.com/openai/v1
export CHAINLIT_AUTH_SECRET=$(chainlit create-secret)
praisonai ui

I get the UI started (after reloading the page - when the browser opens, it says 'page not found')

However, when I'm calling one of the example prompts, I'm getting this error:

ImportError:
CrewAI is not installed. Please install with:
pip install "praisonai[crewai]"

I'm using Linux MINT 22.

I had the same issue. Doing a from crewai import Agents gave me an ImportError: No module named pkg_resources.
Solved that by doing a pip install setuptools.
After that it works.
