Javascript “如何解决错误”；未找到输入模块中的错误：错误：无法解析'；文件'；或'；目录'&引用；你有什么反应？

我是reactjs新手，正在尝试开发简单的应用程序。我正在关注youtube视频以开发基本应用程序

我采用了同样的方法，但我正在windows中开发我的应用程序。当我运行

npm start

时，出现以下错误

下面给出了我的package.json文件

webpack.config.js文件如下

var webpack = require("webpack");
var path = require("path");

var DIST_DIR = path.resolve(__dirname,"dist");
var SRC_DIR = path.resolve(__dirname,"src");

var config = {
    entry: SRC_DIR + "app/index.js",
    output: {
        path: DIST_DIR+ "/app",
        filename: "bundle.js",

    },
    modules: {
        loaders: [
            {

                }
            }
        ]

};

module.exports = config;

如何解决此错误？有人能帮忙吗？

你能把

条目：SRC_DIR+“app/index.js”改成
条目：SRC_DIR+“/app/index.js”吗，
并再次尝试执行
npm运行

npm运行脚本启动npm运行构建

更改为
