我在heroku上部署我的应用时出现问题。我被困住了，找不到答案。我已经完成了heroku故障排除和部署过程。我已经尝试了3天。我已经多次重写我的env文件，每次都这样做，它在localhost上不起作用。我有MONGOD和NODEMON在运行。我恢复原状，它正在工作。但仍然不会在heroku上部署。提前谢谢。
这是我的env.js的样子
module.exports = {
db: process.env.MONGODB_URI || 'mongodb://localhost/sailcast',
port: process.env.PORT || 3000
}

这是heroku日志。我无法弄清楚错误。只是不断收到应用程序错误

答案 0 :(得分：0)
看起来不错。我想到的一件事是，如果您的文件名为app.js或index.js，因为它是npm start的错误？也许你打错了。
我想到的另一件事是，如果您从heroku设置环境数据库值。既然，我看不到您的整个heroku日志，那是另一种可能性
