Agile Web Development with Rails 7: 'rails new demo' specifying the Rails version has no affect

@rubys

Created the demo app with the following command from page 102:

work>​​ ​​rails​​ ​​new​​ ​​demo​ 

Examined the installation with the following command from page 104:

​demo>​​ ​​bin/rails​​ ​​about​ 

Output indicated Rails 7.0.5:

About your application's environment Rails version 7.0.5 

So I deleted the demo directory and ran the command, specifying the version:

rails _7.0.4_ new demo 

Command bin/rails about still reports Rails 7.0.5. However, the Gemfile indicates 7.0.4:

gem "rails", "~> 7.0.4" 

I presume 7.0.4 vs 7.0.5 is not going to make much of a difference. However, it would be nice to understand what’s going here.

FYI, gem list rails --local output:

*** LOCAL GEMS *** importmap-rails (1.1.6) rails (7.0.5, 7.0.4) rails-dom-testing (2.0.3) rails-html-sanitizer (1.6.0) sprockets-rails (3.4.2) stimulus-rails (1.2.1) turbo-rails (1.4.0)
