I got an error while creating a new Rails app (rails new name_project)
问题
It looks like you've successfully resolved the issue by updating the Ruby version in your project's Gemfile to "3.2.2". Everything should be working normally now with the updated Ruby version. If you encounter any further issues, feel free to ask for assistance.

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:
Bundle complete! 15 Gemfile dependencies, 73 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

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?

"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."
"简单的答案是要么更改Gemfile中的版本要求，要么安装Gemfile指定的版本。"
"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."
"然而，我强烈建议您卸载您的Ruby安装，安装一个Ruby版本管理器（RVM，或者现在可能更流行的是RBenv），以这种方式管理您的Ruby安装。在您的Ruby之旅早期进行这样的操作比以后要容易得多。"
