I was following the crew ai tutorial and these are the steps that I have done: 1. Create and activate a python virtual environment, version is 3.11.9 2. Install crewai and crewai tools 3. Create latest-ai-development project 4. Go into the project directory and run `crewai install` I got the following error message: ``` Running the Crew warning: `VIRTUAL_ENV=/Users/jisonz/crew_agent/venv-3.11` does not match the project environment path `.venv` and will be ignored Using CPython 3.13.0 interpreter at: /opt/homebrew/opt/python@3.13/bin/python3.13 Creating virtual environment at: .venv Built latest-ai-development @

You have currently two Python versions installed on your computer. > [@Jason\_Zhang](#): > > ```auto > Using CPython 3.13.0 interpreter at: /opt/homebrew/opt/python@3.13/bin/python3.13 > > ``` This line says that you’re using Python interpreter `v3.13.0`. Although you installed Python `v3.11.9`, you’re using a newer interpreter when running commands, which is not compatible with CrewAI. If you’re using Visual Studio Code, then change the Python interpreter as follows: 1. Press Ctrl + Shift + P on Windows or ⌘ + ⇧ + P on Mac. 2. Type the following command: `> Python: Select Interpreter` 3. Choose the Python interpreter `v3.11.9`. ---
