node.js heroku – app / web.1：错误：没有指定模板
我在我的heroku node.js应用程序中得到这个错误。 它运行良好，突然开始看到这个错误，每当我们尝试访问应用程序，我们得到“内部服务器错误”。 同样的node.js应用程序在我的本地运行良好。 请让我知道如何解决这个问题。 用heroku支持，但他们不能帮助太多。

如果它在本地工作，请检查更新的版本是否破坏了express，dust，adaro等之间的相互兼容性：
rm -rf node_modules npm install --quiet --production npm start
最好在package.json中设置固定版本（ npm install --save --save-exact foobar ）。
我们无法解决这个问题。 与heroku支持团队交谈，被告知应该是一个应用程序问题。 但我们的应用程序在本地开发环境中运行良好 然后，我们在aws中部署了我们的应用程序，作为解决此问题的解决方法。
