css - Sass::Visitors 中的语法错误#new

Question

我是 Ruby 的新手，渴望学习!我现在正在学习顶点 Rails 教程第 1 册中的教程，但遇到了一个小问题。我希望你们能够并且会帮助我。

我已经用 Zurb Foundation 做了一个应用程序，现在教程告诉我要测试它，但是我得到一个错误。我在 Google 上找不到解决方案..
我通过 Nitrous.io 使用 Ruby 2.1.5。
我会添加我看到的所有信息，如果不是这样，我很抱歉，但请告诉我，以便我将来改进!我们开始:

当我启动服务器并想要预览时，
我收到此错误:

**Sass::SyntaxError in Visitors#new**  


*Showing /home/action/workspace/learn-rails/app/views/layouts/application.html.erb where line #7 raised:  
Invalid CSS after "...ules: $modules ": expected "}", was "!global;"  
  (in /home/action/workspace/learn-rails/app/assets/stylesheets/framework_and_overrides.css.scss:13)*

10 <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

应用程序跟踪:

app/assets/stylesheets/framework_and_overrides.css.scss:2
app/views/layouts/application.html.erb:7:in     '_app_views_layouts_application_html_erb___1613058967742566382_40390520'

编辑 5-1-014。这是在 Framework_and_overrides.css.scss

// import the CSS framework
@import "foundation";

// override for the 'Home' navigation link
.top-bar .name {
  font-size: rem-calc(13);
  line-height: 45px; }
.top-bar .name a {
  font-weight: normal;
  color: white;
  padding: 0 15px; }

// THESE ARE EXAMPLES YOU CAN MODIFY
// create mixins using Foundation classes
@mixin twelve-columns {
  @extend .small-12;
  @extend .columns;
  }
@mixin six-columns-centered {
  @extend .small-6;
  @extend .columns;
  @extend .text-center;
  }
// create your own classes
// to make views framework-neutral
.column {
  @include six-columns-centered;
  }
.form {
  @include grid-column(6);
  }
.form-centered {
  @include six-columns-centered;
  }
.submit {
  @extend .button;
  @extend .radius;
  }
// apply styles to HTML elements
// to make views framework-neutral
main {
  @include twelve-columns;
  background-color: #eee;
  }
section {
  @extend .row;
  margin-top: 20px;
  }
