nodejs登錄到控制檯時出錯

Question

我創建了一個在本地機器上運行良好的插件stubbydb。但是，當使用jenkins在遠程服務器上運行時，出現以下錯誤。

因此，直到jenkins工作時間運行stubbydb響應。但詹金斯的工作完成後。它停止工作。並在console.log()聲明上給出錯誤。

如果我登錄到服務器並在節點控制檯上執行console.log("something")。我沒有看到任何錯誤。此外，如果我在登錄後直接運行stubbydb而不是詹金斯。它工作正常。

可能是什麼原因？我應該避免寫入控制檯？

Answer 1

我找不到任何應用程序錯誤。問題自動解決。這似乎與詹金斯工作或服務器設置。不過，我已經刪除了所有的默認console.log並根據需要進行了日誌記錄。所以如果任何人面臨同樣的問題，只需關閉日誌記錄。

Answer 2

嘗試這樣做...

FunctionThrowingException().on("error", function(){ 
     //Handle exception here 
}); 

上拋出異常的功能。我曾經遇到過這個問題，但是有另一個Node的應用。處理異常應該能夠完成這項工作。

P.S.這不是確切的解決方案，因爲您沒有提供完整的代碼。所以，只要採取這個想法，並通過您的代碼。應該幫助。
