我正在运行Rails（v4.2.6）应用程序。当我尝试使用HTTPWebResponse response = (HttpWebRequest)request.GetResponse();
时，应用程序在使用Sass功能时崩溃（即：使用变量）。
它给出的确切错误：
.scss在线
wrong number of arguments (given 0, expected 1) (in .../app/assets/stylesheets/application.scss)
代码导致崩溃 = stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true
（使用变量）
application.scss的Gemfile
$color: #FFF;
a {
color: $color;
}
Gemfile.lock的
# encoding: UTF-8
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

语句，但删除这些语句没有用
使用require输出有效的sass application.scss application.css文件
编辑（22/03/17）： 固定代码中的空格
答案 0 :(得分：0)
删除冒号之前的空格，如下所示：
$color: #FFF;
a {
