登錄後顯示快捷區域錯誤應用程序

Question

我有一個節點快速應用程序作爲前端和一個作爲後端運行的spring/tomcat應用程序。我測試了後端api，並且一切正常，在瀏覽器中，當我提出api請求時，它顯示了json響應。雖然當我在節點推出前端應用程序，並在瀏覽器中輸入的登錄表單憑據（本地主機：3000），形式登錄後它提供了以下錯誤：

Express 
    500 RangeError: port should be >= 0 and < 65536: 8080;

我app.js似乎是罰款。當應用程序啓動它顯示消息：

Express server listening on port 3000 

這是app.js的一部分，我省略與路由做部分：app.get和app.post。

問題出在我的環境變量定義在/ etc/environment中，它有PORT，這是一個用逗號拼寫的拼寫錯誤。 我

REMAX_SERVICE_HOST=localhost:8080;

我固定：

REMAX_SERVICE_HOST=localhost:8080
