RSpec加载所有gem文件

Question

每当我尝试运行我的rspec测试（使用'rspec spec'或'bundle exec rspec spec'）时，屏幕上会显示大量输出。它似乎正在经历我的Gemfile中的每一个宝石，并显示它的消息。以下是该输出的一个例子（还有更多）。

有人可以告诉我这些消息是什么，以及如何阻止他们显示每次我想运行测试？

参见https://github.com/rspec/rspec-core/issues/1571。基本上，最近的rspec版本默认将--warnings添加到.rspec文件。这导致了很多关于gems输出代码的警告。现在的'修复'是删除--warnings行。
