heroku問題：預計「{」，是「$ grayMediumLigh ...」

我遵循rails教程chapter7，一切都很順利，直到我將代碼推送到heroku並按下「heroku open」命令時。然後嘗試運行命令$ heroku logs，得到了以下錯誤消息

我的源文件如下：

application.html.erb 

<!DOCTYPE html>                
<html>                  
    <head>                  
    <title><%= full_title(yield(:title)) %></title>       
    <%= stylesheet_link_tag "application", media: "all" %>     
    <%= javascript_include_tag "application" %>        
    <%= csrf_meta_tags %>              
    <%= render 'layouts/shim' %>            
    </head>                  
    <body>                  
    <%= render 'layouts/header' %>           
    <div class="container">             
     <% flash.each do |key, value| %>          
     <%= content_tag(:div, value, class: "alert alert-#{key}") %>   
     <% end %>                
     <%= yield %>               
     <%= render 'layouts/footer' %>           
     <%= debug(params) if Rails.env.development? %>       
    </div>                 
    </body>                  
</html>

$grayMediumLight存在於文件custom.css.scss文件。它太冗長，所以我只是粘貼部分如下：

custom.css.scss 

@import "bootstrap";     

/* mixins, variables, etc. */   

$grayMediumLight: #eaeaea;    

@mixin box_sizing {      
    -moz-box-sizing: border-box;   
    -webkit-box-sizing: border-box;  
    box-sizing: border-box;    
}          
/* universal */       

html {         
    overflow-y: scroll;                    
}          

body {         
    padding-top: 60px;     
}          
.....

你有鏈接的教程？代碼看起來正確。 – Femaref

http://ruby.railstutorial.org/chapters/sign-up,這是鏈接。而且我也將我的代碼推送到https://github.com/ryuever/sample_app – ryu

提供您已經解決了問題，那麼你需要重新運行bundle exec rake assets:precompile RAILS_ENV=production，使資產能夠被編譯。正如您可能會發現，當您查看public/assets/custom.css.scss時，尚未進行更改。所以一旦你使用提供的命令預編譯你的資產並推送到Heroku主分支，這應該可以解決你的問題。

它不起作用。順便說一句，我找不到文件'公共/資產/ custom.css.scss'，在該文件夾中它只是只有三個文件，如** application-fe10468cdb685128eba66fc59c536a77.js ** – ryu

@oda當你說它不工作，你是指'捆綁exec資產：預編譯RAILS_ENV =生產'？我相信通常當你預編譯你的資產時，你最終應該得到一個'application.css'文件，就像http://i.imgur.com/tGwKl6c.png – David

抱歉讓你感到困惑，我的意思是即使我有重新編譯如你所說（可能它應該是'bundle exec rake assets：precompile RAILS_ENV = production'），但是這個問題仍然沒有解決。然後我發現所有的語句突然在文件'app/assets/stylesheets/application.css' – ryu
