node.js heroku - app/web.1 : Error: no template specified

Question

我在 Heroku Node.js 应用程序中收到此错误。它运行良好，但每当我们尝试访问该应用程序时，突然开始看到此错误，并收到“内部服务器错误”。相同的 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。与 Heroku 支持人员交谈，但他们帮不上什么忙。

Answer 1

在代码中的某个位置，您调用了 adaro 的 engine() 函数，但没有提供 file 参数:

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

如果它在本地工作，请检查更新版本是否没有破坏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)。
