Question

我一直在尝试在appname＆＃39; picbookapp＆＃39;下部署一个nodejs应用程序。在heroku上有一个mongo数据库。对于mongodb，我使用了mlabs，我已经将mONGO_URI添加到我的heroku app中的配置变量中。我还添加了Procfile文件。但由于某些原因我收到错误。因为我是新手应用程序部署任何类型的帮助将非常感激。这是几个错误日志 开始：未找到代码ELIFECYCLE， errrno ENOENT，文件sh，系统调用生成，产生ENOENT 这是packag.json文件 -

    "passport-local": "^1.0.0"
  },
  "engines": {
    "node": "4.1.1",
    "npm": "5.0.3"
  }
}

这是database.js

/**

var mongodb=require('mongodb');
var MongoClient=mongodb.MongoClient;
var url=process.env.MONGOLAB_URI||'mongodb://localhost:27017/imageDatabase';

function getDb(){
     return MongoClient.connect(url).then(function (db) {
        // console.log(MongoClient.connect(url));
        return db;
    })
}




module.exports=getDb();
