Error for implementing routing

I’m trying to use the routing feature of Illuminate/Routing included as experimental in Sage theming. I’ve activated the environment variable in my .env file by setting it to true. I’ve created a ‘routes’ folder with a file named ‘web.php’ inside it, where I’ve defined some basic routes. However, when I run the ‘wp acorn route:list’ command, it tells me that I don’t have any registered routes. Does anyone have a tutorial on how to use routing?

I would try:

$ wp acorn optimize:clear
$ wp acorn route:list
