Ruby on rails 为什么即使我从未使用过minitest，也会出现此minitest错误？

当我运行我的规范时，我得到了这个错误，即使我的代码中从未包含minitest：

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

这是rails 4 master

下面是我的spec_helper.rb的顶部：

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

这是堆栈跟踪：

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

最新版本的Minitest（内置于Ruby中）在RSpec方面有一些突破性的变化

这里有一个与此问题相关的github问题

---

将minitest gem添加到您的gem文件是一项临时工作

---

另一个选择是指向rspec rails的github主版本，因为我相信它已经在那里得到了修复。

Minitest与

ruby 1.9

及更高版本捆绑在一起

Rails

只需借助ruby附带的

ruby

谢谢，我已经更新了我的回复。我知道它在Rails中，但没有意识到它在CoreRuby中。不过，我的回答的其余部分是正确的。“将minitest gem添加到您的gem文件是一项临时工作。”-这不会有什么区别，因为minitest版本被rails锁定为4.2。我目前正在探索使用RSpecRails的GithubMaster，尽管当前版本使用RSpec3.0pre，所以这是一个很大的飞跃。我正在试着看看我是否能把所有的部分组合在一起……我仍然在rspec rails 3.0.0-beta中遇到这个错误。约翰·巴彻运气好吗？
