RSpec LoadError

Question

我正在尝试在CodeEval上练习编写测试以应对挑战。每当我创建一个文件夹时，我都会在项目文件夹中创建'lib‘& 'spec’文件夹。在命令行中运行：

rspec --init

它告诉我'spec/spec_helper.rb‘& '.rspec’是创建的。我将源文件放在'lib‘文件夹中，而spec文件放在'spec/lib’文件夹中，并相应地命名它们。下面是一个规范的示例：

require 'spec_helper'
require 'file_name'

describe '#swap_elements' do
  it 'should swap 1 pair of numbers' do
    swap_elements('1 2 3 4 5 6 7 8 9',0,8).should == '9 2 3 4 5 6 7 8 1'
  end
end

在项目的根目录中，我运行：

rspec /spec/lib/file_name_spec.rb

其结果如下：

/Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load': cannot load such file -- /spec/lib/swap_elements_spec.rb (LoadError)
from /Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `block in load_spec_files'

from /Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/runner.rb:17:in `block in autorun'

这是最近的一个问题&我没有安装任何更新的rspec宝石。知道为什么会这样吗？

Answer 1

在路径开始处使用斜杠意味着根。

你想做什么

rspec spec/lib/file_name_spec.rb

因此，它将搜索当前目录。
