环境：VMware上的Ubuntu系统

不知道是否使用因为VMware的问题，这次安装Ruby和Rails时遇到了非常多问题。在网上查询时，也遇到了很多没有提供解决方法的博主。因为现在我找到了解决方法，就在这总结一下我所遇到的问题吧。
首先，我终于看到这个页面啦！！！

Ruby on Rails

一般的安装过程

1. 使用apt-get安装最新版本的ruby

sudo apt-get update 
sudo apt-get install ruby2.3

• 使用apt-get安装ruby的依赖包

sudo apt-get install ruby2.3-dev

• 使用gem安装Rails

sudo gem install rails

• 安装Rails的依赖包

sudo apt-get install libsqlite3-dev 
sudo gem install sqlite3 
bundle install
sudo apt install ruby-railties

• 在Rails中创建新的工程，并进入创建的工程。

rails new [project_name]
cd [project_name]

• 启动server，测试Rails是否安装成功。在浏览器中访问http://localhost:3000。

rails server
