Ruby on rails 3.2 保存一个打开的页面无法工作-错误消息表明找不到方法-但为什么？

我在另一个标题下发布了这个请求，在我用信息更新请求后没有收到任何反馈

我正在一个私人项目中工作，我是一名学习Rails的开发人员，并尝试使用TDD/BDD做正确的事情，但我必须说的是，我的经历让我想放弃测试，因为我根本没有时间尝试解决环境问题

我花了24小时的大部分时间试图解决这个问题。以下是我尝试过的事情：

删除Gemfile.lock并重新安装捆绑包

删除了gemeset并从头开始

按照教程（M.Hartl的从头开始）重建我的部分环境

昨晚——当我从本地项目切换到开始为主机更新git版本的一些功能时，drb选项失败了（因为我还是新手，所以我正在运行两个项目和两个git文件夹）

我有[

open_and_save_page

]在本地项目中工作，但在开始下一阶段交付之前，当我运行我的规范来测试所有内容时，我遇到了与--drb相关的故障，所以我升级了，当我打开防护流程时，这似乎消失了

以下是当前的错误：

我不确定我是否以正确的方式发布了我的问题，因为在其他一些问题上，我没有得到任何回应。在所有这些方面仍然是新的，在这方面的帮助是巨大的。所以先谢谢你

我需要做什么才能让第二个项目顺利进行

我注意到的一件事是，自从我开始在.rvmrc文件中放入[

use

]之后，当我将cd放入目录时，我得到了以下内容

打开和保存页面

]是一种水豚方法吗？launchy在这一切中的位置是什么？我认为这是一个黄瓜相关的宝石。

我认为这是一个新的用户理解错误。我发现，如果我将[

save\u and\u open\u页面

]放在

it

块中，我就可以实现这一点

---

我在阅读的任何文档中都没有看到这一点，但我想这是有道理的。

刚刚注意到，如果您之前没有访问…\u路径，则保存和打开页面甚至不存在，因此，像这样在块外调用它肯定是错误的。刚才注意到，如果您以前没有执行

访问…\u path

，则保存和打开页面甚至不存在，因此像这样在块外调用它肯定是错误的
