我想開始學習 Ruby on Rails。我已經通過 RVM 安裝了 ruby?? 2.7.0。SQLite3 也默認安裝在 ubuntu 20.04.3 LTS 中。我的 Rails 版本是 7.0.2.2。當我運行命令時：
rails new blog
來自本指南： https ://guides.rubyonrails.org/getting_started.html
它拋出一個錯誤：
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 "."

我找不到與我相關的問題，所以我希望有人可以幫助我。
uj5u.com熱心網友回復：
我解決了我的問題。看起來它也需要安裝 git。
