NodeJS Heroku部署錯誤

Question

當我從github將我的應用程序部署到Heroku時，在我的Heroku儀表板上，它說我的應用程序已成功部署。 但是，當我查看我的應用程序時，它說應用程序錯誤。

所以這是我的日志：

這是我的server.js以防萬一：

var express = require('express');
var app = express();

app.use(express.static(__dirname + '/public'));

var server = app.listen(80, function () {
  var port = server.address().port;
  console.log('Listening at port ' + port);
});

我是Heroku的新手，請幫幫我，謝謝。

Answer 1

而不是80，嘗試使用這樣（process.env.PORT || 80））

Answer 2

常見問題，試試這個。

在應用程序的根目錄中添加一個文件：Procfile它沒有擴展名，只有Procfile

在此Procfile中，添加以下內容

web: node ./bin/www

重新編譯並重新注入，讓我們知道會發生什么。
