今天在學(xué)習(xí)webpack的知識。然后學(xué)到構(gòu)建本地服務(wù)器出現(xiàn)的問題。這是我的配置代碼：module.exports = { devtool:'eval-source-map',entry:  __dirname + "/app/main.js",//已經(jīng)多次提及的唯一入口output: {    path: __dirname + "./public",//打包后文件存放的地方     filename: "bundle.js",    devServer:{        contentBase:"/public",        historyApiFallback:true,        inline:true    }}}這是package.json的代碼：{"name": "webpack","version": "1.0.0","description": "","main": "index.js","dependencies": {"webpack": "^4.6.0"},"devDependencies": {"webpack-cli": "^2.1.2","webpack-dev-server": "^3.1.4"},"scripts": {"start": "webpack","test": "echo \"Error: no test specified\" && exit 1","server": "webpack-dev-server --open"},"author": "","license": "ISC"}看了報錯確實沒看懂，也網(wǎng)上搜了很久，還是沒搞懂。求各位大哥賜教。
