body: <p>I am building a simple rails app and when I load the home page I get:</p>
  
  <pre>
      Completed 500 Internal Server Error in 59ms
      ActionView::Template::Error (different prefix: "c:/" and
      "D:/workspaceRor/jrpappthree/ ssets/stylesheets" 
      (in D:/workspaceRor/jrpappthree/app/assets/stylesheets/custom.css.scss)):

  <pre><code>2: &lt;html&gt;

  <p>my gem file</p>
  
  <pre><code>gem 'rails'
  gem 'bootstrap-sass'
  gem 'bcrypt-ruby'
  gem 'faker'
  gem 'will_paginate'
  gem 'bootstrap-will_paginate'
  gem 'pg'
  group :development, :test do
  gem 'mysql2'
  gem 'annotate'
  end
  # Gems used only for assets and not required
  # in production environments by default.
  group :assets do
  
  gem 'sass-rails'
  gem 'coffee-rails'
  gem 'uglifier'
  gem 'railties'
  end
  gem 'jquery-rails'
  group :test do
  
  end
  
  group :production do
  #  gem 'pg'
  end
  </code></pre>
  
  <p>in D:/workspaceRor/jrpappthree/app/assets/stylesheets/custom.css.scss</p>
  
  <pre><code>@import "bootstrap";
  
  
  body {
     padding-top: 60px;
  }
  .
  .
  .
  </code></pre>
  
  <p>In development environment, it shows the above error, but in production it works fine.
  I even tried </p>
  
  <pre><code># config/environments/production.rb
  ...
  config.assets.compile = true
  ...
  </code></pre>
  
  <p>but it didnt solve my problem.
  So what will be the solution for running the app in development env. successfully?        </p>
