Question

我在英雄上手动部署了一个应用程序（之前从未完成过，只是将它连接到我的github存储库）。它说成功部署但我得到了错误：

An error occurred in the application and your page could not be served. Please   
try again in a few moments.
If you are the application owner, check your logs for details.

我的日志是：

我的服务器：

var chalk = require('chalk');
var db = require('./db');
var server = require('http').createServer();

var createApplication = function () {
    var app = require('./app')(db);
    server.on('request', app); // Attach the Express application.
    require('./io')(server);   // Attach socket.io.
};

var startServer = function () {
    var PORT = process.env.PORT || 1337;

    server.listen(PORT, function () {
        console.log(chalk.blue('Server started on port', chalk.magenta(PORT)));
    });
};

db.sync().then(createApplication).then(startServer).catch(function (err) {
   console.error(chalk.red(err.stack));
});

我的procfile：

web: node server/start.js

server / env / index.js：

var path = require('path'); var devConfigPath = path.join(__dirname, './development.js'); 
var productionConfigPath = path.join(__dirname, './production.js'); 
var testConfigPath = path.join(__dirname, './testing.js');     
if (process.env.NODE_ENV === 'production') { module.exports =   
require(productionConfigPath); } 
else if (process.env.NODE_ENV === 'testing') { module.exports = require(testConfigPath);    } 
else { module.exports = require(devConfigPath); }

这是什么意思？我研究过具有相同问题的帖子和提出的答案，但没有什么真正有帮助..

您可以尝试setting the Node and NPM versions与本地使用的相同（工作地点）。

另外请确保您没有错过dev依赖项，因为除非explicitly configure to do so，否则Heroku不会安装它们。

更新：

从您的评论中看来，当您在Heroku等生产环境中运行代码时，数据库URL将从名为return _context.Section.Include(x => x.Leagues.Select(y => y.Games.Where(v=>v.GameStart > DateTime.Now))).ToList();的环境变量中获取。您可以在DATABASE_URI上更改此变量以匹配添加插件时添加到应用程序的env var的键，或者您可以创建具有所需值的环境变量。有关更多信息，请阅读this
