在我的Rails应用程序中,我将
Ruby从1.9.3更新到2.1.0.现在,当我重新开始测试时,我收到一个错误：
NameError: uninitialized constant MiniTest::Unit::TestCase::SUPPORTS_INFO_SIGNAL
以下是Gemfile中的宝石：
gem 'rails' gem 'MysqL2' gem 'json' gem 'jquery-rails' gem 'kaminari' gem 'therubyracer' gem 'devise' gem 'rak' gem 'rails-translate-routes' gem 'routes' group :assets do gem 'sass-rails'," ~> 3.2.3" gem 'uglifier',' >= 1.0.3' end group :development,:test do gem 'factory_girl_rails' end group :test do gem 'shoulda' gem 'database_cleaner' gem 'capybara' end
这是堆栈跟踪：

解决方法
我刚刚遇到一个与此类似或相同的错误,并且能够在本地解决它.对我来说,我的痕迹始于：
/home/youruser/.rvm/gems/ruby-2.1.0/gems/mocha-0.10.5/lib/mocha/integration/mini_test/version_230_to_262.rb:19:in `run': uninitialized constant MiniTest::Unit::TestCase::SUPPORTS_INFO_SIGNAL (NameError)
这表明当mocha尝试引用从可能与Ruby升级一起出现的minitest版本中删除的常量时,错误实际上发生在mocha中.
对我来说,做一个捆绑更新摩卡修复了这个问题.
做了一些代码,专门找出问题得到解决的地方,我在mocha存储库的克隆副本上使用了“git pickaxe”(git log -SSUPPORTS_INFO_SIGNAL),它看起来像是this commit removed the reference to SUPPORTS_INFO_SIGNAL,所以在提交之后使用任何东西在摩卡应该没问题.
如果升级您的mocha版本无法解决问题,请仔细查看堆栈跟踪,您应该看到哪个库中依赖于SUPPORTS_INFO_SIGNAL的minitest导致错误.然后查看该依赖关系的上游,看看是否修复了这个问题.如果没有,请将您正在使用的依赖项展示为表现出此行为,并将您自己的补丁推送到上游.
