我正在使用 Michael Hartl Ruby on Rails 教程。目前第 10 章。当我创建代码以向用户添加微博并尝试运行测试时，我收到此错误：

我的 user_pages_spec.rb 文件如下所示：

require 'spec_helper'

describe "User pages" do

    end    
  end

        specify { user.reload.email.should == new_email}
      end
    end
  end

这个问题的明显结果是没有向用户添加微博。错误似乎与用户创建有关，但我真的不知道如何处理它。

我遇到了同样的问题——微博在浏览器中渲染得很好，但是同样的测试失败了。原来问题是我有一个错字UsersController#show- 我是通过params[:id]而不是params[:page]to @user.microposts.paginate。

通过将我的代码与 GitHub 上的源代码进行比较，我发现了问题所在。

我也被这个困住了。当我比较 Github 上的参考代码中的规范时，我注意到我没有使用let!（参见user_pages_spec.rb的第 80 行）。

这在上一节 (10.1) 中提到过，其中let延迟加载其对象。

尝试更改describe "User pages" do为describe "User pages", :js => true do. 这解决了你的问题吗？
