Answer 1

i recently install fastapi,uvicorn and tried to run

uvicorn main:app --reload

I am using zsh (shell type does not matter) and pyenv for virtual environment

got the same trouble (zsh: uvicorn command not found)

Solution which worked for me

python -m uvicorn main:app --reload

Why it worked

its because when we install uvicorn it install some system binaries which we may have to add to the path for the terminal to catch

else, we need to let the the terminal know about the binaries through python
