node.js heroku - app/web.1：錯誤：未指定模板

Question

我在我的heroku node.js應用程序中收到此錯誤。它運行良好，突然開始看到這個錯誤，每當我們嘗試訪問應用程序，我們得到「內部服務器錯誤」。同樣的node.js應用程序在我的本地運行良好。請讓我知道如何解決這個問題。支持heroku支持，但他們沒有多大幫助。

Answer 1

我們無法解決此問題。與heroku支持團隊交談，並被告知它應該是一個應用程序問題。但是我們的應用在本地開發環境中運行良好。然後，我們在aws中部署了我們的應用程序，作爲解決此問題的解決方法。

Answer 2

在你的代碼

某處，你調用阿達羅的engine()功能，無需提供file的說法：如果它的工作在本地，檢查更新版本

• https://github.com/krakenjs/adaro/blob/467ec9aa8cc00a9326ed50cd3ca7fc3ac2b20ee3/lib/engine.js#L134

沒有express，dust，adaro等之間的互相兼容性：

rm -rf node_modules 
npm install --quiet --production 
npm start 

最好在package.json中設置固定版本（npm install --save --save-exact foobar）。
