Mongoose / MongoDB錯誤：無法確定服務器的狀態

Question

突然間，我在本地運行我的應用程序時開始出現此錯誤。 據我所知，上次工作和現在之間沒有任何變化。 它似乎是數據庫層上的錯誤，因為它發生在應用程序嘗試執行某些與數據庫相關的任務時。

我試過升級節點，npm，mongoose，mongodb，我仍然得到同樣的錯誤。

我可以提供很多信息，但我不知道哪些是最相關的，所以讓我知道還有什么需要幫助解決這個問題。

我還附上了我目前的package.json

Answer 1

事實證明，當我切換到使用Yarn而不是NPM來處理模塊時，我在不知不覺中更新了我的Node版本。 我不得不安裝節點v6.1.3。
