使用RSpec获取未初始化的常量错误.不知道是什么原因造成的 [英] Getting an uninitialized constant error with RSpec. Have no idea what's causing it

问题描述

我正在使用RSpec进行测试，周五下午我离开工作时，我的测试通过了.但是当我回家并同步存储库时，笔记本电脑上的测试失败了.现在恢复工作，测试仍然失败.不要相信它是我的代码，因为单独运行rspec会返回错误，spork甚至无法启动.当我尝试启动Spork时，出现以下错误消息:

I'm using RSpec for testing and when I left work Friday afternoon, my tests were passing. But when I went home and synced my repository, the tests failed on my laptop. Now back at work, the tests are failing still. Don't believe its my code since running rspec by itself returns an error and spork won't even start up. When I try to start Spork, I get the following error message:

Using RSpec
Loading Spork.prefork block...

有人知道这可能是什么原因吗?

Anyone know what could be causing this?

推荐答案

我遇到了这个问题.在spec_helper.rb中尝试替换:

I ran into this problem. In the spec_helper.rb try replacing:

require "rails"

使用

require "rails/all"

在我的情况下工作.
