I am working on Michael Hartl Rails tutorial (currently chapter 7). When I try to run server this message appear:

Sass::SyntaxError in Static_pages#home

Showing C:/rails_project/sample_app/app/views/layouts/application.html.erb where line      #5 raised:

Invalid CSS after "}": expected "}", was ""
(in C:/rails_project/sample_app/app/assets/stylesheets/custom.css.scss)

Extracted source (around line #5):

2: <html>
3:   <head>
4:     <title><%= full_title(yield(:title)) %></title>
5:     <%= stylesheet_link_tag    "application", media: "all" %>
6:     <%= javascript_include_tag "application" %>
7:     <%= csrf_meta_tags %>
8:     <%= render 'layouts/shim' %>

app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_html_erb___917874405_26658636'

Code from application.html.erb:

<!DOCTYPE html>
<html>
  <head>
    <title><%= full_title(yield(:title)) %></title>
    <%= stylesheet_link_tag    "application", media: "all" %>
    <%= javascript_include_tag "application" %>
    <%= csrf_meta_tags %>
    <%= render 'layouts/shim' %>    
  </head>
  <body>
    <%= render 'layouts/header' %>
    <div class="container">
      <%= yield %>
      <%= render 'layouts/footer' %>
      <%= debug(params) if Rails.env.development? %>
    </div>
  </body>
</html>

I have no idea where is the problem. Error message seem to inadequate to code existing in aplication.html.erb. Anyone got clue?

    The error is in your style sheet:

    app/assets/stylesheets/custom.css.scss

    Your app is using Sass (http://sass-lang.com) and there is a problem in the file listed above. Fix the .scss error and the error message will go away. Unfortunately, it does not appear to give you an errant line number within that .scss file.
