ruby-on-rails - 如何在没有弃用警告的情况下运行 rspec

Question

但是，每当我尝试运行时，我都试图遵循“ RSpec 入门 - 第 1 部分”

rspec

我收到：

我是 Rspec 的新手。我检查了ruby -v：

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]

然而，gem -v结果是：

3.1.3

我尝试安装 Nokogiri 并修复Gem::ConfigMap已弃用的问题，但似乎没有任何效果。

我应该如何运行测试？

一段时间以来，我在加载我的“calculator_spec.rb”测试时遇到了问题，无论是否使用“spec_helper”，您展示的本教程“RSpec 简介 - 第 1 部分”非常简单。如果您按照步骤操作，此问题不在 spec_helper 中，而在于您在文本编辑器中的编写方式。我使用 sublime，尽量不要给 Ctrl + C - V，键入代码，因为引号，空格可以在解释器之后以不同的方式解释。至于弃用的gem，您使用的是rspec 3.1版，您的帖子没有当前版本3.9那么旧，请不要在Gemfile中指定版本，因为它会自动安装最新版本。

建议：使用更新版本的 ruby​​。最好使用 RVM。按照提供的教程进行操作，无需复制和粘贴，现在不要做任何超出范围的操作。（没有安装spec_helper）。
