问题描述
我正在尝试将我的一个 Rails 项目升级到 Ruby 1.9.2
.一切都很顺利,但一项 RSpec 测试失败了.在这个测试中,我需要
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
...
lib 看起来像这样:
The lib looks like this:
# file lib/services/my_lib.rb
class MyLib
def self.do_something
...
在 Ruby 1.8.7 (REE) 中,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 无法找到该库.
I have no clue, what keeps Ruby 1.9 from finding the lib.
推荐答案
ruby 1.9 中的加载路径与 1.8 中的加载路径不同.
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您的加载路径中.
You need to add the project's root directory to your load path.
你可以通过像这样运行 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
...或者通过手动向 spec_helper.rb
中的加载路径添加内容(将其放在 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
目录添加到加载路径中,因此您可以改写如下 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'
这篇关于使用 Ruby 1.9.2 在 RSpec 中需要 lib 带来“没有这样的文件要加载";的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
