为什么rake_test_loader.rb在RVM ruby​​版本2.2.1下的Rake中运行测试时失败（LoadError）

标签： ruby rake rvm

我刚开始使用RVM并安装了ruby 2.2.1版。我有一个测试项目，其Rake测试任务我成功地使用系统版本（2.0.0）执行测试。当我通过RVM切换到2.2.1时，rake_test_loader失败并出现LoadError。

据我所知，以下是可能的罪魁祸首

  1. 正在使用的不同版本的Ruby
  2. RVM环境导致问题
  3. RVM和Rake存在问题

    4. 我的代码被打包成标​​准的gem结构。 rake文件如下：

    ($LOAD_PATH << File.expand_path("../lib", __FILE__)).uniq!

require 'rake/testtask'
require 'rdoc/task'
require 'rubygems/package_task'

# Run All Tests Task
#
Rake::TestTask.new('test') do |t|
  t.pattern = 'test/**/*tests.rb'
  t.warning = true
end

task "default" => ["test"]

    确切的错误（设置了--trace标志）如下：

    我不确定上面的跟踪是否有用，所以当在系统ruby版本2.0.0和RVM ruby​​版本2.2.1下运行测试时，我显示了$ LOAD_PATH

    在RVM ruby​​版本2.2.1下测试失败时，

    $ LOAD_PATH：

    "/Users/Sancho/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0",
"/Users/Sancho/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/x86_64-darwin14",

"/Users/Sancho/dev/git/joy/lib"
    测试在2.0.0下传递时

    $ LOAD_PATH：

    "/Library/Ruby/Site/2.0.0",
"/Library/Ruby/Site/2.0.0/x86_64-darwin13",
"/Library/Ruby/Site/2.0.0/universal-darwin13",

"/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13",
"/Users/Sancho/dev/git/joy/lib"

    项目的根目录是/ Users / Sancho / dev / git / joy /

    测试位于/ Users / Sancho / dev / git / joy / test /.../*_ tests.rb

    测试中的代码位于/ Users / Sancho / dev / git / joy / lib / joy /.../*。rb

    总而言之，在两个场景中都执行相同的代码（由rake测试任务调用），1个传递另一个失败。第一种情况是使用ruby的系统版本（版本2.0.0，通过），第二种情况是RVM ruby​​版本2.2.1（失败）。

    那么，是什么导致了LoadError问题呢？

    感谢。

    更新：

    我已经通过RVM安装了版本2.0.0p598（而不是系统版本2.0.0p481。（我不得不使用p598，因为p481不再可用）。 使用版本2.0.0p598，测试工作正常。这排除了RVM本身就是一个问题，让我相信最新版本的ruby 2.2.1存在问题。任何人都可以对此有所了解吗？

    更新2号： Ruby版本2.1.1p76也可以。
