Redis – I got an error while creating a new Rails app (rails new name_project)

So I installed Ruby and Rails through this video (https://www.youtube.com/watch?v=fmyvWz5TUWg&t=9163s&ab_channel=freeCodeCamp.org) and I was making a new Rails app by using the command rails new <name of the project>. At the end, the app is created, but there are these errors at the end:

It seems like this error is about the version of ruby, but what should I do to resolve this? Would this error affect me in any way?

EDIT

I went to the Gemfile of the project, and changed from ruby "3.1.2" to ruby "3.2.2", then deleted the whole project and create a new project again using rails new <project_name>. And then I got this:

Bundle complete! 15 Gemfile dependencies, 73 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
         run  bundle binstubs bundler
       rails  importmap:install
Add Importmap include tags in application layout
      insert  app/views/layouts/application.html.erb
Create application.js module as entrypoint
      create  app/javascript/application.js
Use vendor/javascript for downloaded pins
      create  vendor/javascript
      create  vendor/javascript/.keep
Ensure JavaScript files are in the Sprocket manifest
      append  app/assets/config/manifest.js
Configure importmap paths in config/importmap.rb
      create  config/importmap.rb
Copying binstub
      create  bin/importmap
       rails  turbo:install stimulus:install
Import Turbo
      append  app/javascript/application.js
Pin Turbo
      append  config/importmap.rb
Create controllers directory
      create  app/javascript/controllers
      create  app/javascript/controllers/index.js
      create  app/javascript/controllers/application.js
      create  app/javascript/controllers/hello_controller.js
Import Stimulus controllers
      append  app/javascript/application.js
Pin Stimulus
Appending: pin "@hotwired/stimulus", to: "stimulus.min.js", preload: true"
      append  config/importmap.rb
Appending: pin "@hotwired/stimulus-loading", to: "stimulus-loading.js", preload: true
      append  config/importmap.rb
Pin all controllers
Appending: pin_all_from "app/javascript/controllers", under: "controllers"
      append  config/importmap.rb
Run turbo:install:redis to switch on Redis and use it in development for turbo streams

Now when I go check for the Gemfile of this newly created project, it now has ruby "3.2.2". So is everything working normal now?

    Check your instaled version with ruby -v in terminal and also check a file challed Gemline, there is a ruby version inside this file.
    Your installed ruby version and Gem file ruby version must be the same

    Well the easy answer is just to say you can either change the version requirement in Gemfile, or else install the version that Gemfile is specifying.

    However, I strongly urge you to remove your ruby installation, install a ruby version manager (RVM, or probably RBenv is the more popular these days) and manage your ruby installations this way. It’s much easier to do it early in your Ruby adventure than later.
