我对使用 Ruby on Rails 运行网站非常陌生。一点背景故事：
所以我正在做一个项目，并且我已经获得了该网站的代码。我正在运行 Windows，所以我知道它不是 RoR 的最佳操作系统，但切换到不同的操作系统对我来说是最后的手段。
我从 railsinstaller.org 获得了 RailsInstaller，然后运行了它。一切安装顺利。
我bundle install从我的站点目录中运行，遇到了 gem "therubyracer" 的问题。做了一堆搜索，发现Windows不需要gem。我认为。所以我将 Gemfile 中的 gem 注释掉，然后bundle install再次运行。一切安装正常。
我尝试rails s通过命令提示符运行并收到错误：
The program can't start because LIBMYSQL.dll is missing from your computer.
所以我对此做了一些研究，发现我必须将文件复制到 RailsInstaller 目录下的 Ruby/bin 文件夹中。错误消失了。
最后我又跑rails s了，服务器放到了localhost下。我认为。无论如何，我去localhost:3000并收到了 MySQL2::Error 和Can't connect to MySQL server on 'localhost' (10061). 当我点击Full Trace我得到代码：

我对此进行了一些研究，发现Rails development - Can't connect to MySQL server on 'localhost' (10061)。
当我尝试ping localhost使用命令提示符时，我得到了最上面的评论：
Reply from ::1: time<1ms
而且我不确定如何更改配置以使主机成为 127.0.0.1。
抱歉，这有点长，我不确定它有多大帮助。正如我在标题中所说，我对此很陌生 - 我仍然不确定 ahost是什么。
我真的只想让网站运行起来，这样我终于可以开始工作了。我做的一切都正确吗？我真的需要therubyracer吗？我做了什么/没有做哪些可以帮助我开始的事情？错误显示什么问题？
如果还有什么我需要提供的，请告诉我！谢谢您的帮助！
