Problems running Rails

Rails
1

Good evening,

Following a tutorial, I installed rails on my Ubuntu and created a new
project using the “rails” command. After starting the built-in server,
if I go to http://localhost:3000, I get the Rails welcome screen.
But after creating a controller with “./script/generate controller hello
index”, when I go to http://localhost:3000/hello, the following appears
in the console:

  • → /hello
    #<ArgumentError: Anonymous modules have no name to be referenced by>

I tried reinstalling Ruby and Rails, but it didn’t work.

Can someone give me a light?

Thanks.
