Error encountered when running rails new command-CodePudding

I want to start learning Ruby on Rails. I have installed ruby 2.7.0 via RVM. SQLite3 is also installed by default in ubuntu 20.04.3 LTS. My rails version is 7.0.2.2. When I run the command:

rails new blog

from this guide: https://guides.rubyonrails.org/getting_started.html

It throws an error:

lou@lou-VirtualBox:~$ rails new blog
      create  
      create  README.md
      create  Rakefile
      create  .ruby-version
      create  config.ru
      create  .gitignore
      create  .gitattributes
      create  Gemfile
         run  git init from "."

I can't find issue related to mine, so I hope someone could help me out.

I solved my problem. It looks like it also needs git installed.
