我在一个文件夹中有两种风格的规范，其中一种使用全脂 rails 环境，使用 rspec，另一种是轻量级助手，需要单独使用 gem。
最近我在 Rubymine 中同时运行这些文件时遇到了一些问题。
右键单击任一样式的单个文件运行良好。右键单击文件夹并选择“运行>文件夹中的所有规范”已为每个规范返回此错误：

直到最近，这一直很好地结合在一起。
我可以从命令行运行所有规范，没有任何问题：
rspec --pattern spec/models/auto_ordering/*_spec.rb
这似乎是在 Rubymine 中运行此文件夹的特定内容。我已尝试使缓存无效并重新启动 IDE。我尝试删除运行该文件夹的配置。
有谁知道这可能是什么原因造成的？
更新：从那以后，我发现通过命令行调用它时似乎偶尔会发生这种情况。
