Question

早上好，抱歉耽误了您的时间，但这确实很重要。我试图上传我的应用程序“MEAN JS”，但在将其上传到 heroku 时出现错误。我将非常感谢您的贡献。非常感谢。

这是我项目的结构，你也可以看到heroku显示的错误：

这是我的节点 package.json：

这是我的文件“index.js”的代码

const express=require('express');
const config=require('./config/config');
const app =config(express()); 
const morgan=require('morgan');
const cors=require('cors');


const multer = require('multer');
const uuid = require('uuid/v4');
const path = require('path');

app.set('views', path.join(__dirname, 'views'));

const storage = multer.diskStorage({
    destination: path.join(__dirname, 'public/img/uploads'),
    filename: (req, file, cb, filename) => {

        cb(null, uuid() + path.extname(file.originalname));
    }
}) 
app.use(multer({storage}).single('image'));
app.use(express.static(path.join(__dirname, 'public')));


//Iniciando el servidor
app.listen(app.get('port'),()=>{
    console.log('Server on port',app.get('port')); 
});

//Llamar a la base de datos
require('./database');

//Funciones

app.use(morgan('dev'));
app.use(express.json()); // Reconocer el formato JSON 
app.use(cors({origin:'http://localhost:4200'}));
