Raspbian returns command not found when running sudo daphne

Question

Goal is to run daphne on port 443.

When I run the following:

sudo daphne -e ssl:443:privateKey=/etc/ssl/mycerts/apache.key:certKey=/etc/ssl/mycerts/apache.pem myProject.asgi:application

The following error is generated:

sudo: daphne: command not found

running which sudo returns /usr/bin/sudo -- sudo is installed.

running which daphne returns /home/pi/.local/bin/daphne -- daphne is installed.

echo $PATH returns **/home/pi/.local/bin**:/lib/python3.9:/usr/local/sbin:/usr/local/bin:/usr/sbin:**/usr/bin**:/sbin:/bin:/usr/local/games:/usr/games

So, both /usr/bin and /home/pi/.local/bin are on the path.

I can run daphne on port 8001 (without sudo) without any problems (ex. daphne -b 0.0.0.0 -p 8001 myProject.asgi:application)

Why does the error command not found appear if sudo is installed, daphne is installed and both locations are on the PATH?

Answer 1

The trouble is when you sudo your executing the command as a different user (normally root) and daphne isn't on that user's path. Try sudo /home/pi/.local/bin/daphne.
