这是我使用“heroku logs --tail”命令收到的记录。有没有人以前有过这种情况，并且知道可能导致问题的原因吗？我找不到解决办法。

其实我的电脑里已经安装了fs-extra模块，应用程序在本地运行正常，但是在Heroku里就不行了。

在这里我附上了我的 index.js 文件的代码，以便您了解我是如何进行设置的：

const { Router } = require('express');
const router = Router();

const Photo = require('../modules/Photo');

const cloudinary = require('cloudinary');
cloudinary.config({
    cloud_name: process.env.CLOUDINARY_CLOUD_NAME,
    api_key: process.env.CLOUDINARY_API_KEY,
    api_secret: process.env.CLOUDINARY_API_SECRET
});

const fs = require('fs-extra');

router.get('/', async(req, res) => {
    const photos = await Photo.find(); //Nos trae todas las fotos almacenadas en MongoDB.
    console.log(photos);
    res.render('images', { photos });
});

router.get('/images/add', async(req, res) => {
    const photos = await Photo.find(); //Nos trae todas las fotos almacenadas en MongoDB.
    res.render('image_form', { photos });

});

router.post('/images/add', async(req, res) => {
    console.log(req.body); //Informacion de la imagen
    const { title, description } = req.body;
    console.log(req.file); //Imagen
    const result = await cloudinary.v2.uploader.upload(req.file.path);
    console.log(result);
    const newPhoto = new Photo({
        title: title,
        description: description,
        imageURL: result.url,
        public_id: result.public_id
    });
    await newPhoto.save();
    await fs.unlink(req.file.path);
    res.redirect('/images/add');
});
router.get('/images/delete/:photo_id', async(req, res) => {
    const { photo_id } = req.params;
    const photo = await Photo.findByIdAndDelete(photo_id); //Eliminar la información de la base de datos.
    const result = await cloudinary.v2.uploader.destroy(photo.public_id); //Eliminar la información subida a Cloudinary. 
    console.log(result);
    res.redirect('/images/add');

});

module.exports = router;

您好，欢迎来到 StackOverflow。请花一些时间阅读帮助页面，尤其是名为"What topics can I ask about here?" 和"What types of questions should I avoid asking?" 的部分。更重要的是，请阅读the Stack Overflow question checklist。您可能还想了解Minimal, Complete, and Verifiable Examples。

【解决方案1】：

其实我的电脑里已经安装了fs-extra模块

这无关紧要。安装在您计算机上的模块对 Heroku 有何影响？

您的依赖项必须全部在您的package.json 和package-lock.json 或yarn.lock 中定义。

将fs-extra 和任何其他依赖项添加到您的package.json，
运行npm install或yarn，
提交您更新的package.json 并锁定文件，
然后再次部署。

Heroku 将在构建过程中安装这些文件中列出的依赖项。

这也可能是个问题：

PORT = 4000

但由于您尚未分享您的server.js，因此很难确定。 Heroku populates the PORT environment variable 这是你的服务器必须绑定的端口。

【讨论】：

嗨 Chris，我实际上已经意识到我在 4000 中的端口配置有错误。所以我设置了一系列环境变量，以便我可以以正确的方式与 Heroku 交互。发生的情况是我仍然有错误，应用程序还没有运行并给我一个类似的日志。
端口提示是为了帮助您解决可能的下一个问题。您的问题的答案在这里的第一部分：将fs-extra 添加到您的依赖文件并重新部署。
谢谢克里斯，我现在就去做。检查我在 index.js 文件中上传的代码。
