Ruby on rails 3 RubyonRails教程（mhartl）"；第10章：销毁用户“；自动测试rspec删除'；摧毁'；失败

我正在做迈克尔·哈特尔的Rails教程第10章的screencast+在线图书，我被困在最后一个子章

控制台输出：

Failures:

我是一个初学者，但在发布任何问题之前，我总是有做大量研究的习惯（90%的时间我通过搜索SO和Google找到答案）

我的最后两个未列出的问题（在发布前找到了答案）通过更新我的GemFile（rspec中的will_paginate和undefined_selector）得到了修复。也会是这样吗

感谢您的关注，并花时间阅读本文

找到了修复上述问题的打字错误（duh！）：

def destroy
    User.find(params[:id]).destroy
    redirect_to users_path, :flash => { :success => "User destroyed." }
  end

我没有选择“users\u path”，而是选择了“users.path”

在尝试从浏览器中删除时注意到它
