将 minitests/reporters 添加到 test_helper.rb - 错误消息答案

【问题标题】：Adding minitests/reporters to test_helper.rb - error message将 minitests/reporters 添加到 test_helper.rb - 错误消息

【问题描述】：

所以这有点超出我的知识范围。我通过执行以下操作将 minitests/reporters 添加到 test_helper.rb：

我安装了 minitest 记者 gem：gem install minitest-reporters 并在test_helper.rb 中添加了require：

require "minitest/reporters"
Minitest::Reporters.

当我运行测试时，我得到的结果是：我应该重新安装所有的 gems 吗？

【问题讨论】：

您是否费心阅读错误信息？ Run rails db:migrate to create it, then try again. 是否也将记者 gem 添加到 Gemfile 中。？
我做了 gem install minitest-reporters 但我没有在 gemfile 中看到 minitest

标签： ruby-on-rails ruby rubygems

【解决方案1】：

这就是我所做的，它奏效了：

1- 在 test_helper.rb 中添加了以下内容：需要“minitest/记者” Minitest::Reporters.use！

2- 在 Gemfile 中添加了以下内容：宝石'minitest'，组：：测试 gem 'minitest-reporters'，组：：测试

3- 运行 rails 测试
