Heroku節點應用程序在驗證部署時意外掛起

Question

節點應用程序在本地一切正常，但是在執行git push時顯示永無休止地持續驗證部署？

它發生了三次，沒有成功或錯誤消息

如您在錯誤日志中所見

2017-01-23T12:33:34.343427+00:00 app[web.1]: npm ERR! missing script: start

您的package.json文件沒有聲明任何start命令。

為了確定如何啟動您的應用，Heroku首先尋找一個Procfile。 如果Node.js應用程序不存在Procfile，我們將嘗試通過package.json中的啟動腳本啟動默認的Web進程。 Web進程類型中的命令必須綁定到PORT環境變量中指定的端口號。 如果沒有，則測功機將不會啟動。

您應該指定它，以使Heroku能夠啟動您的應用程序：

"scripts": {
  ...
  "start": "node server.js"
  ...
}

更新＃1：

嘗試刪除Procfile ，然后在package.json ：

"scripts": {
  "start": "node server/app.js",
  "postinstall": "bower install && ./bin/www staging"
}

Heroku將運行npm install ，它將執行postinstall命令中存在的bower install 。
