javascript - 错误：在 Function.Module._resolveFilename 中找不到模块“配置”

Question

Hii 我有简单的节点服务器，结构如下

myapp
 -config 
    -default-json
 -index.js
 -package-lock.json
 -package.json

这是我的 index.js 的一部分

'use strict';

const
    config = require('config'),
    express = require('express'),
    request = require('request'),
    body_parser = require('body-parser'),
    app = express().use(body_parser.json()); // creates express http server

// Sets server port and logs message on success
app.listen(process.env.PORT || 1337, () => console.log('webhook is listening'));

当我运行 node index.js 时，出现以下错误

internal/modules/cjs/loader.js:583
    throw err;
    ^

Error: Cannot find module 'config'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15)
    at Function.Module._load (internal/modules/cjs/loader.js:507:25)
    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:22:18)

    at Module._compile (internal/modules/cjs/loader.js:689:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:700:10)
    at Module.load (internal/modules/cjs/loader.js:599:32)
    at tryModuleLoad (internal/modules/cjs/loader.js:538:12)
    at Function.Module._load (internal/modules/cjs/loader.js:530:3)

我的代码有什么问题？

您必须在您的中明确添加配置模块package.json：

"dependencies": {

  "config": "version number"
}
