error facing while running fastapi application

Solution

  • Your uvicorn seems to be outside your virtualenv (the use of which being evident from (env) in your prompts), in ~/.local (your user site-packages directory). Remove it, then install and use an uvicorn within your env.

    1. Without env activated: pip uninstall --user -y uvicorn
    2. With your env activated: pip install uvicorn

    You might also want to check for other packages that shouldn't have been installed outside a venv: pip list --user and similarly uninstall them to avoid further conflicts.

    You can also set PIP_REQUIRE_VIRTUALENV=false in your environment variable settings to prevent you from accidentally installing packages outside a virtualenv in the future.
