unable to run camping

[arvindcj]

I followed the Getting Started section of the book and got this error while running camping.

camping Version: camping (3.1.3)
Ruby Version ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin17]

Book: https://github.com/camping/camping/blob/main/book/02_getting_started.md

Steps to reproduce

1. gem install camping
2. follow the first step in the Getting started section.
3. Notice the error.

Btw i did notice a difference in the 'bin/camping' file present on rubygems and the main branch of github. The file looks different.

[arvindcj]

it looks like a person new to the project, needs to follow the steps in the README.md and then the book.
