module.js:491 抛出错误； 错误：找不到模块“www/node-str/index.js”

Question

我遇到了这个问题，我无法解决，据我所知，我没有发现任何错误，但我是初学者，所以我不太了解，这是代码：

[nodemon] starting `node index.js`
module.js:491
throw err;
^

Error: Cannot find module '/www/node-str/index.js'
at Function.Module._resolveFilename (module.js:489:15)

[nodemon] app crashed - waiting for file changes before starting...

应用程序.js

 const express = require('express');
 const bodyParser = require('body-parser');

 const app = express();
 const router = express.Router();


 const index = require('./routes/index');
 const products = require('./routes/products')

 app.use(bodyParser.json());
 app.use(bodyParser.urlencoded({ extended: false}));

 app.use('/', index);
 app.use('/products', products);

 module.exports = app;

索引.js

 'use strict';

 const express = require('express');
 const router = express.Router();

 router.get('/', (req, res, next) => {
 res.status(200).send({ title: "Node Store API", version: "0.0.1" });
 });

 module.exports = router;

你的 package.json 是：

"main": "src/app.js"
