Ruby on rails 3 Rails测试错误-NameError:TestCase:：支持信息信号

在我的Rails应用程序中，我将Ruby从

1.9.3

更新为

2.1.0

。现在，当我重新启动测试时，我得到一个错误：

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

以下是堆栈跟踪：

我刚刚遇到了一个与此类似或相同的bug，并且能够在本地解决它。对我来说，我有一个开始的痕迹：

/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试图引用一个常量时，该错误实际上发生在mocha中，该常量已从minitest版本中删除，该版本很可能与Ruby升级一起出现

对我来说，做一个

包更新摩卡

修复了这个问题

我做了一些代码探索来找出问题的具体解决方法，在mocha存储库的克隆副本上使用了“git pickaxe”（

git log-SSUPPORTS\u INFO\u SIGNAL

），看起来像是这样，所以在mocha中使用提交之后的任何东西都可以

如果升级您的mocha版本无法解决问题，请仔细查看堆栈跟踪，您应该会看到哪个库依赖于定义了SUPPORTS\u INFO\u信号的minitest导致了错误。然后查看该依赖关系的上游，看看这个问题是否得到了解决。如果没有，请将显示此行为的依赖项分叉，并将自己的修补程序推到上游。

不幸的是，它对我不起作用，我用最新的version@pukoo您能提供完整的堆栈跟踪吗？在Github/minitest上报告问题后，zenspider建议使用最新的mocha gem，因为它是一种“摩卡咖啡”虫。就我而言，我没有在我的文件中直接使用“摩卡”。但另一种宝石“水豚”对摩卡咖啡有依赖性。我也在Gemfile中声明了“mocha”Gem，它可以使用ruby 1.9.3和ruby-2.0.0-p481
