vue-cli3新建脚手架；启动项目后webpack报错如何解决？

Question

1.通过vue-cli3.0命令创建一个项目；项目目录如下

添加vue.config.js配置文件；代码如下；

module.exports = {
    publicPath: "/",
    outputDir: "dist",
    assetsDir: "assets",
    indexPath: "index.html",
    filenameHashing: true,
    pages: undefined,
    lintOnSave: true,
    runtimeCompiler: false,
    transpileDependencies: [],
    productionSourceMap: false,
    crossorigin: undefined,
    integrity: false,
    devServer: {
        index: 'main.html',
        contentBase: __dirname,
        open: process.platform === 'darwin',
    },
}

启动项目后

项目可以正常打开运行；但是出现的3个错误如何解决？

1. webpack output is served from /
2. Content not from webpack is served from E:projectvuex_demo
3. 404s will fallback to /index.html

我尝试过改变vue.config.js配置；但是并没有解决，请问一下这个需要怎么配置？

Answer 1

devServer: {
    index: 'main.html',
    contentBase: __dirname,
    open: process.platform === 'darwin',
}

看这里 给的是main.htm  但你目录里面似乎没有  

Answer 2

我能说根本就没有报错吗？那只是四个info提示而已。
