javascript - Heroku Node.js 服务器在运行 npm start 脚本时出错
问题描述
我已经在 heroku 上运行了一年没有任何问题的服务器，但是在上次部署时，它在运行时出现错误，信息很少npm start，除了模块更新之外，回滚构建和这个新部署之间几乎没有变化，但是一个有效，另一个无效。
我更新了我的包，明确说明了我的 NPM 和 Node 版本（如下所示，我的 package.json 文件），并测试了多个回滚以查看它们有什么不同（这似乎没什么）。由于错误发生在我的服务器代码之前（如下所示），我什至不知道从哪里开始诊断。
node server.js除了运行不起作用之外，控制台几乎没有提供任何解释：

这是我的package.json文件：

}
服务器本身似乎根本没有激活，因为通常我会收到信息消息。该错误似乎发生在代码之前，我想知道我是否错过了一些小东西。
server.js即使它根本没有被击中：
const express = require('express'); // Import of EXPRESS to create routing app
const http = require('http'); // Import of the NODE HTTP module to create the http server
const { logger } = require('./middleware/log/winston'); // Import of winston for error logging
logger.info('Starting boot-up for WTS Game server...');
require('supports-color'); // Allows colors for debug panel
// Start up proceesses
logger.info('Loading Start-up proceesses...');
const app = express(); // Init for express
logger.info('Express app started...');
const server = http.createServer(app); // Creation of an HTTP server
logger.info('HTTP server created...');
require('./middleware/log/logging')(); // Bootup for error handling
require('./routes/sockets')(server); // Starts websocket
require('./routes/routes')(app); // Bootup for Express routes
require('./middleware/mongoDB/db')(); // Bootup of MongoDB through Mongoose
require('./config/config')(); // Bootup for special configurations
require('./middleware/production/prod')(app); // Production compression and middleware
app.use(express.static('public'));
const port = process.env.PORT || 5000; // Server entry point - Node Server
server.listen(port, () => logger.info(`WTS Server started on port ${port}...`));
代码在开发环境中运行良好，直到这个合并在 heroku 上运行良好，没有实际的错误来诊断我不知道为什么它现在不能启动。任何帮助都会很棒。
