Rake測試後發生錯誤，紅寶石在軌道上

Question

我遵循rails tutorial Hartl https://www.railstutorial.org/book/static_pages#sec-getting_started_with_testing並且安裝了所需的所有東西，並且目前爲止它工作正常，除非我每次運行rake test。

測試運行，但之後我得到一系列錯誤，如下所示。我不知道這些是什麼以及如何解決它們。

任何想法？

Answer 1

是否使用TMUX？如果沒有，那麼我會刪除配置，告訴tmux在測試完成後通知您。這個配置可能在test_helper.rb中，但很難知道你沒有看到你正在關注哪個教程。

Answer 2

安裝tmux實際上解決了我的問題！
