Question

Alex Chaffee的测试优先红宝石课程教授如何使用rspec。我目前仍然坚持第一次练习，00_hello。我按照说明创建了一个文件hello.rb，其中包含代码：

def hello
   "Hello!"
end

并将其放在00_hello目录hello_specs.rb中。当我从目录rake在终端中键入00_hello时，我收到以下错误，这些错误与rspec错误不同：

我猜我的设置有问题。以下是我正在使用的版本。

Mac OS 10.8.2
Ruby版本1.9.3
rake 0.9.2.2
rspec version 2.12.2

Answer 1

检查00_hello文件夹的目录结构。它应该是这样的

 ├── hello.rb
 ├── hello_spec.rb
 └── index.html

由Rakefile提供的

learn_ruby负责为加载路径添加正确的目录，因此您不必担心它，除非您在不理解的情况下将其更改为某个地方。

如果您仍然遇到问题，请发布Rakefile此处

Answer 2

如果它对任何人有帮助，我在ruby 1.9.3上遇到了完全相同的问题。我的解决方案有三个方面：

运行gem install rspec; bundle update; bundle install
CD转入00_hello，然后修改require行以阅读require './hello'
运行rspec hello_spec.rb

Answer 3

您是否尝试过从测试优先课程的根目录运行rake？

也有一半可能是正确的，也许他们一直在运行ruby 1.8，其中包含.到$ LOAD_PATH，而你运行的是1.9.3但是没有这样做，因为{{1}不需要等等。
