rails未初始化的常量Sprockets :: SassCacheStore [英] rails uninitialized constant Sprockets::SassCacheStore

问题描述

我的情况是，我在我的网站上有这个导航菜单，并且还有一些其他的功能，我需要选择current_page链接..而不是建立一个帮手我想安装一个gem，所以我去找了一个，发现

然后我跟着文档说了什么：

在我的gemfile我添加了
gem'rack_current_page'

然后在项目根目录 config.ru

  require :: File.expand_path（'../ config / environment'， __FILE__）
使用Rack :: CurrentPage 
 run Rails.application 
  

最后我跑了：

bundle 和 rails s only to发现我有这个错误：
$ b $ 未初始化的常量Sprockets :: SassCacheStore

我使用下列软件包/版本（只列出可能会有影响的内容 - 如果我'我错过了一些东西让我知道）

（< gem> -v）

• Rails 4.2.1


• Sprockets 3.0.0


• Sass 3.4.13


• Rack 1.5

删除我添加的每一行 - 赫克我也重置我的项目文件头，因为我刚开始工作，无论如何，
运行一个新的包，重新启动服务器，检查网站，但我所得到的是上述错误..

我搜索并尝试寻找类似的问题，所以找不到任何这样的事情，我唯一真正可以尝试的是卸载并重置我的git 。

我确实在寻找一些非常愚蠢的东西，但无法真正在这里找到答案;）

$ b $如果我错过了你们需要的信息，请提前和评论。

任何帮助都很好， p>

我实际上做了一个快速的 gem pristine --all ，但没有结果。

好的，因为在短时间内重新创建了一个新应用程序，因此在猜测和发生相同情况之前，我卸载了 compass-rails gem并运行 bundle 之后 rails s 来测试是否开始工作。

它的确如此。然后，我继续重新安装 compass-rails ，它一直在工作......现在变得非常困惑：S

我发现了这个问题，并且通过实际提供的解决方案解决了这个问题。

解决方案

使用rails 4.2的版本。

默认的 gem compass-rails 会安装与链轮不兼容的版本。 / p>

当我添加特定版本时，可以看到 ，然后运行另一个 bundle 我在问题中命名的大部分软件包的版本都发生了变化。

在包含gemfile修改后的控制台输出：

 安装链轮2.12。 3（3.0.0）
使用sprockets-rails 2.3.1（是2.2.4）
安装sass-rails 5.0.1（5.0.3）
安装compass-rails 2.0 .4（是2.0.1）
  
 
 
 
猜测它只是在等待指南针发布兼容版本。
 
I'm new to rails and trying to do some playing around with gems and such.

My case here is that I have this navigation menu on my website and I needed to get the current_page link selected.. rather than building a helper I wanted to install a gem so I went and looked for one and found this one.

I then followed what the documentation said:

In my gemfile I added
gem 'rack_current_page'

Then in the project root config.ru
require ::File.expand_path('../config/environment', __FILE__)
use Rack::CurrentPage
run Rails.application
And finally I ran:

bundle and rails s only to find out I had this error:

uninitialized constant Sprockets::SassCacheStore

The error happens when including the application stylesheet in the layout file.

I'm using the following packages / versions (only listing what might have impact - if I'm missing something let me know)

(<gem> -v)


Rails 4.2.1
Sprockets 3.0.0
Sass 3.4.13
Rack 1.5


While doing the uninstall I removed every line I added - heck I also reset my project files to head since I just started working on it anyways,
ran a fresh bundle, restarted the server, checked the site but all I'm getting is the error above..

I googled and tried to look for a similar question on SO but couldn't find any so the only thing I could really try was the uninstall and reset my git.

I'm definitely looking over something really stupid but can't really find the answer so here I am ;)

Any help is appriciated, thanks in advance and comment if I missed info that you guys need.

time of writing

I actually did a quick gem pristine --all with no results either.

EDIT 1

Okay, so with abit of guesswork and the same situation happening before resulting in the recreation of a fresh app in the (short) past I uninstalled the compass-rails gem and ran bundle afterwhich rails s to test if things started working.

It did. Then I went on and reinstalled compass-rails and it kept working... getting quite confused now :S
解决方案
Okay so here goes:

I've found the problem and it was solved by actually supplying a version that works with rails 4.2.

The default gem compass-rails installs a version incompatible with sprockets.

When I added the specific version as seen here and ran another bundle the versions of most of the packages I named in the question changed.

console output after gemfile modification included:
Installing sprockets 2.12.3 (was 3.0.0)
Using sprockets-rails 2.3.1 (was 2.2.4)
Installing sass-rails 5.0.1 (was 5.0.3)
Installing compass-rails 2.0.4 (was 2.0.1)
Guess it's just waiting for compass to release a compatible version.
