Bench setup production user error

To avoid installing frappe-bench v15 using

pip install frappe-bench --break-system-packages

used the method python venv
all steps went fine
but

(myenv) frappe@localhost:~/frappe-bench$ bench setup production frappe
WARN: superuser privileges required for this command

when sudo given

(myenv) frappe@localhost:~/frappe-bench$ sudo bench setup production frappe
sudo: bench: command not found

got this error
any clues to overcome it

fix the issue for
bench setup production in python venv
by using this

(myenv) frappe@localhost:~/frappe-bench$ sudo -E env PATH="$PATH" bench setup production frappe

it works
