【中文标题】Windows 上未初始化的常量 Sprockets::SassCacheStore 错误（学习 ruby on rails 书）【英文标题】：uninitialized constant Sprockets::SassCacheStore Error on Windows (Learn ruby on rails book) 【发布时间】：2015-09-12 14:32:07 【问题描述】：我是 Web 开发的新手，我一直在学习 David Kehoe 在 Windows 机器上的学习 ruby on rails 教程。在过去的几天里，我一直遇到同样的错误，我尝试了几乎所有可以在互联网上找到的解决方案。
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><%= content_for?(:title) ? yield(:title) : "Learn Rails" %></title>
<meta name="description" content="<%= content_for?(:description) ? yield(:description) : "Learn Rails" %>">
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%# Modernizr is required for Zurb Foundation %>
<%= javascript_include_tag 'vendor/modernizr' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
问题出在这行：
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
我已经安装了 NodeJs，我认为问题出在任何 javascript 文件上，因为如果我去掉那一行，它可以在没有 css 的情况下工作。我也尝试过删除没有帮助的 require 树。
这是我的 Gemfile：
source 'https://rubygems.org'
ruby '2.1.5'
gem 'rails', '4.2.2'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
# learn-rails
gem 'activerecord-tableless'
gem 'compass-rails', '~> 2.0.alpha.0'
gem 'figaro'
gem 'gibbon'
gem 'google_drive'
gem 'high_voltage'
gem 'simple_form'
gem 'zurb-foundation'
group :development do
gem 'better_errors'
gem 'quiet_assets'
gem 'rails_layout'
end
还有application.css.scss：
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.
*
*= require_tree .
*= require_self
*/
还有其他人遇到过这个问题并找到了解决方案吗？
这是当前错误的堆栈跟踪。由于某种原因，它从错误的争论数量（1 比 2）变为（3 比 2）：

【问题讨论】：
【参考方案1】：您使用的是旧的 alpha 版本的指南针，这是 known issue。
看完这个 Github Issue 听起来 gems 的工作组合是：
gem 'sass-rails', '~> 5.0'
gem 'compass-rails', '~> 2.0.4'
应该可以的。
【讨论】：
感谢您的回复。好的，我在我的 Gemfile 中将 compass-rails 更改为 2.0.4，我还必须将 Sass-rails 更改为 5.0.1 但现在我在命令行中收到此错误：C:/RailsInstaller/Ruby2.1.0/lib/ ruby/gems/2.1.0/gems/sass-rails-5.0.1/lib/sass/rails/helpers.rb:11:in `我刚刚点击了这个，以下对我有用（正如 Zuru 在子评论中提到的那样 - 发布以便于阅读）。
gem "compass-rails", github: "Compass/compass-rails", branch: "master"
gem 'sprockets', '2.11.0

您在 sprockets 版本号后面缺少引号，我想添加它，但由于它太短，修改堆栈溢出拒绝我的编辑以上是关于Windows 上未初始化的常量 Sprockets::SassCacheStore 错误（学习 ruby on rails 书）的主要内容，如果未能解决你的问题，请参考以下文章
