I have a repository: GitHub - joskoot/hanoi: GUI for playing the game of The Tower of Hanoi · GitHub
It depends on graphics/graphics.

When I try to install it with DrRackets package manager I get the following error:

What can I do about it?

Look at Matthew's answer:

The graphics/graphics library relies on racket/base/gui so requiring "hanoi.rkt" in the scribble file require racket/base/gui twice.

As a first experiment, remove the non-for-label "hanoi.rkt" and see what happens.

@(require
   scribble/core
   scribble/eval
   racket
   "hanoi.rkt"
   (for-label
     "hanoi.rkt"
     racket
     (only-in typed/racket Setof Natural Sequenceof Index))
   (for-syntax racket))

This might not be enough though - I remember running into the same issue when I wrote the documentation for sketching and it was a bit tricky to get around the issue.

I kept the for label require, but removed the plain require of hanoi.rkt. That works.
Thanks very much.
