New Phoenix project on Ubuntu getting [error] backend port not found: :inotifywait

Question

I created a new phoenix project and when I run mix phoenix.server, I get

[error] backend port not found: :inotifywait

in red in my console. This looks menacing and, since I haven't really done anything yet, seems like the type of thing that should work.

Answer 1

You need to add the inotify backend. Please see the readme here and you should be quickly on your way: https://github.com/phoenixframework/phoenix_live_reload#backends
