Question

当我运行“rails server”命令并转到我的网页时，我收到此错误http://s7.postimg.org/jcxqxl3gr/image.png我正在使用Postgresql并且只安装了twitter-bootstrap-rails gem。我使用的是rails 4.0.0。为什么它会向我显示此错误？我通过railsinstaller安装了所有东西，但是通过rubygems更新到4.0.0。

任何帮助都会受到重视，

阿玛尔

我认为你的postgres服务器没有运行。为什么你会遇到这个错误尝试运行它。你正在使用Windows，所以尝试检查这个链接它会给你一些提示

postgreSQL database service

Ruby on Rails页面加载错误“无法连接到服务器：连接被拒绝（0x0000274D / 10061）”
