<％= render'shared / error_messages'％>

我在另一个文件中使用相同的语法，可以。
解决方案
 
  form_for（@user），：html => ... 
  
在 @user ，关闭对 #form_for 方法的调用，因此它不知道如何处理逗号和散列。
 
 
 
更改为：
  form_for（@user，：html => ...）do | f | 
  
你会很好。甚至没有括号：
  form_for @user，：html => ... do | f | 
  
 
I don't get why this return me a error
<%= form_for(@user), :html => {:class => 'form-connexion'} do |f| %>
  <%= render 'shared/error_messages' %>

  <%= f.label :name %>
  <%= f.text_field :name %>

  <%= f.label :email %>
  <%= f.text_field :email %>

  <%= f.label :password %>
  <%= f.password_field :password %>

  <%= f.label :password_confirmation, "Confirm Password" %>
  <%= f.password_field :password_confirmation %>

  <%= f.submit "Save changes", class: "btn btn-large btn-primary" %>
<% end %>

I'm using the same syntax in another file and it's ok.
解决方案
form_for(@user), :html => ...
That end bracket, after @user, closes the call for the method #form_for, so it doesn't know what to do with the comma and then the hash.

Change that to:
form_for(@user, :html => ...) do |f|
And you'll be good. Or even no brackets:
form_for @user, :html => ... do |f|
