在我的 Rails 应用程序中，我已将 Ruby 从 更新1.9.3为2.1.0. 现在，当我重新启动测试时，出现错误：

NameError: uninitialized constant MiniTest::Unit::TestCase::SUPPORTS_INFO_SIGNAL

这里有宝石Gemfile：

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：

我刚刚遇到了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，我有一个开头的痕迹：

/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 尝试引用一个常量时，错误实际上发生在 mocha 中，该常量已从可能与 Ruby 升级一起出现的 minitest 版本中删除。

对我来说，做一个bundle update mocha固定的问题。

做了一些代码探索以明确问题的解决位置，我git log -SSUPPORTS_INFO_SIGNAL在 mocha 存储库的克隆副本上使用了“git pickaxe”（），看起来这个提交删除了对 SUPPORTS_INFO_SIGNAL 的引用，所以在之后使用任何东西mocha 中的提交应该没问题。

如果升级你的 mocha 版本不能解决问题，请仔细查看堆栈跟踪，你应该看到哪个依赖 minitest 并定义了 SUPPORTS_INFO_SIGNAL 的库导致了错误。然后在该依赖项中查看上游以查看此问题是否已解决。如果没有，请分叉您正在使用的表现出此行为的依赖项并将您自己的补丁推送到上游。
