Phusion错误：未定义的方法`有？'对于Sass :: Util：模块

问题描述

在加载网页时，我收到了由Phusion发出的以下错误：

 尝试加载宝石'指南针轨道'。 
 Gem Load Error是：对于Sass :: Util：模块
有未定义的方法`has？'您的意思是？散列
散列
用于宝石加载错误的Backtrace是：
 /Volumes/Data/htdocs/zetcho/vendor/bundle/gems/compass-0.12.2/lib/compass/sass_extensions/functions/ urls.rb：5：in`has？'
  

指定位置的代码是：

 模块Compass :: SassExtensions :: Functions :: Urls 
 
 
 def self.has？ （base，instance_method）
 Sass :: Util.has？（：instance_method，base，instance_method）
 end 
  

我的gem文件包含：

 ＃Bundle edge Rails改为：gem'rails'，github： 'rails / rails'
 gem'rails'，'〜> 5.1.2'
 
＃使用mysql作为活动记录的数据库
 gem'mysql2'，'〜> 0.3.18'
 
＃在样式表中使用SCSS 
 gem'sass-rails'，'〜> 5.0'
 
＃将Compass用于样式表
 gem'compass-rails'
 
＃使用Compass扩展名susy 
 gemsprockets
 gem'susy'
  

我刚刚使用Rails 5.1.2创建了Ruby on Rails网站，红宝石2.3.1。我有一个很老的网站，可以很好地与宝石。我是否错过了整体安装的一个步骤，或者这是一个使用compass-rails的bug？

当我尝试添加控制器时，出现同样的错误：

  rails generate controller home index 
  

经过更多的挖掘，我发现了一个类似的问题。我通过将gem文件更改为：

  gem'compass-rails'，github：'Compass / compass-rails '
  

然后：

  rm gemfile.lock 
包
  

I get the following error issued by Phusion when loading a web page:

There was an error while trying to load the gem 'compass-rails'.
Gem Load Error is: undefined method `has?' for Sass::Util:Module
Did you mean?  hash
               Hash
Backtrace for gem load error is:
/Volumes/Data/htdocs/zetcho/vendor/bundle/gems/compass-0.12.2/lib/compass/sass_extensions/functions/urls.rb:5:in `has?'

The code at the indicated location is:

module Compass::SassExtensions::Functions::Urls


def self.has?(base, instance_method)
  Sass::Util.has?(:instance_method, base, instance_method)
end

My gem file contains:

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.1.2'

# Use mysql as the database for Active Record
gem 'mysql2', '~> 0.3.18'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'

# Use Compass for stylesheets
gem 'compass-rails'

# Use the Compass extension susy
gem "sprockets"
gem 'susy'

I've just created the Ruby on Rails site using Rails 5.1.2 and ruby 2.3.1. I have a much older site that works fine with the gem. Did I miss a step in the overall install or is this a bug with compass-rails?

I got the same error when I tried to add a controller:

rails generate controller home index

解决方案

After more digging around, I found a similar problem. I fixed this one by changing the gem file to:

gem 'compass-rails', github: 'Compass/compass-rails'

Then:

rm gemfile.lock
bundle
