ruby-on-rails ruby

Ruby on rails Rails抱怨缺少括号，而我不希望有括号,ruby-on-rails,ruby,erb,Ruby On Rails,Ruby,Erb,我得到以下错误： Showing app/views/layouts/application.html.erb where line #15 raised: app/views/layouts/application.html.erb:15: syntax error, unexpected keyword_end ');@output_buffer.append= ( end );@output_buffer.safe_concat('

我得到以下错误：

Showing app/views/layouts/application.html.erb where line #15 raised:
app/views/layouts/application.html.erb:15: syntax error, unexpected keyword_end  
  ');@output_buffer.append= ( end );@output_buffer.safe_concat('
                             ^
app/views/layouts/application.html.erb:22: syntax error, unexpected keyword_ensure, expecting ')'
app/views/layouts/application.html.erb:24: syntax error, unexpected keyword_end, expecting ')'

Extracted source (around line #15):
12: <div class="container">
13:   <%= flash.each do |key, value| %>
14:       <div class="alert alert-<%= key %>"><%= value %></div>
15:   <%= end %>
16:   <%= yield %>
17:   <%= render 'layouts/footer' %>
18: </div>

显示app/views/layouts/application.html.erb，其中第15行出现：
app/views/layouts/application.html.erb:15:语法错误，意外的关键字\u结束
');@输出_buffer.append=（结束）@输出缓冲区安全连接（'
^
app/views/layouts/application.html.erb:22:语法错误，意外关键字_sure，应为“'）”
app/views/layouts/application.html.erb:24:语法错误，意外关键字_end，应为“'）”
提取的源（第15行附近）：
12: 
13:   
14:       
15:   
16:   
17:   
18:

下面是application.html.erb的内容

<!DOCTYPE html>
<html>
<head>
  <title><%= 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| %>
      <div class="alert alert-<%= key %>"><%= value %></div>
  <%= end %>
  <%= yield %>
  <%= render 'layouts/footer' %>
</div>
</body>
</html>

试试：

试试：



 <% flash.each do |key, value| %>
   <div class="alert alert-<%= key %>"><%= value %></div>
 <% end %>

<% Ruby code -- inline with output %>
<%= Ruby expression -- replace with result %>
<%# comment -- ignored -- useful in testing %>
% a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)
%% replaced with % if first thing on a line and % processing is used
<%% or %%> -- replace with <% or %> respectively
