I want to start ruby server.

I install:

gem install bundler

gem install sqlite3

gem install webpacker

gem install rails

And I create a new rails application.

gem new test_app

Also it's time to run server:

cd test_app

rails server

But I take error shown below

=> Booting Puma
=> Rails 7.0.3 application starting in development
=> Run `bin/rails server --help` for more startup options
