RSpec LoadError

Question

我正在尝试为CodeEval上的挑战练习编写测试.每个挑战我正在创建一个文件夹,在项目文件夹中创建'lib'和'spec'文件夹.从我运行的命令行:

rspec --init

它告诉我'spec/spec_helper.rb'和'.rspec'已创建.我将源文件放在'lib'文件夹和'spec/lib'文件夹中的spec文件中并相应地命名它们.这是一个规范的例子:

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

从我运行的项目的根目录:

rspec /spec/lib/file_name_spec.rb

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/configuration.rb:819:in `each'
from /Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load_spec_files'
from /Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/command_line.rb:22:in `run'
from /Users/username/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.13.1/lib/rspec/core/runner.rb:80:in `run'
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,我还没有安装任何更新的rspec宝石.知道为什么会这样吗？

在路径的开头使用斜杠表示根.

你想做

rspec spec/lib/file_name_spec.rb

所以它将搜索当前目录
