使用Ruby 1.9.2的RSpec中的require lib会带来“没有此类文件可加载". [英] require lib in RSpec with Ruby 1.9.2 brings "no such file to load"

问题描述

我正在尝试将我的Rails项目之一升级到Ruby 1.9.2.一切都进行得很好，但是一项RSpec测试失败了.在此测试中，我require一个Ruby lib:

I am trying to upgrade one of my Rails projects to Ruby 1.9.2. All went pretty well, but one RSpec test broke. In this test I require a Ruby lib:

# file spec/models/my_lib_spec.rb
require 'spec_helper'
require 'lib/services/my_lib'

describe "MyLib" do

  it "should do something" do
...

库看起来像这样:

# file lib/services/my_lib.rb
class MyLib

  def self.do_something
  ...

在Ruby 1.8.7(REE)中，该测试运行良好:

In Ruby 1.8.7 (REE) the test worked well:

$ ruby -v   
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin11.1.0], MBARI 0x6770, Ruby
Enterprise Edition 2011.03
$ rspec ./spec/models/my_lib_spec.rb
..

Finished in 1.4 seconds
2 examples, 0 failures

在Ruby 1.9.2中，我得到一个错误no such file to load:

In Ruby 1.9.2 I get an Error no such file to load:

$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
$ rspec ./spec/models/my_lib_spec.rb
/Users/tmangner/.rvm/gems/ruby-1.9.2-p290@madgoal/gems/activesupport-
3.2.2/lib/active_support/dependencies.rb:251:in `require': no such file
to load -- lib/services/my_lib (LoadError)

我不知道，是什么让Ruby 1.9无法找到lib.

I have no clue, what keeps Ruby 1.9 from finding the lib.

推荐答案

ruby​​ 1.9中的加载路径无法像在1.8中那样完全起作用.

The load path in ruby 1.9 doesn't work exactly like it did in 1.8.

您需要将项目的根目录添加到加载路径.

You need to add the project's root directory to your load path.

您可以通过运行rspec来做到这一点:

You can do this by either running rspec like this:

rspec -I . ./spec/models/tipp_remember_spec.rb

...或通过手动将内容添加到spec_helper.rb的加载路径中(将其放置在spec_helper.rb

...or by manually adding stuff to the load path in your spec_helper.rb (put this at the top of your spec_helper.rb

$:<< File.join(File.dirname(__FILE__), '..')

我认为rspec默认情况下也会将您的本地lib目录也添加到加载路径中，因此您可以改写如下的require行:

I think rspec by default adds your local lib directory to the load path as well, so you might be able to rewrite the require line as follows instead:

require 'services/my_lib'
