打包出错：Tip: built files are meant to be served over an HTTP server.
Opening index.html over file:// won't work

npm run dev是开发环境, npm run build是生产环境, 在开发环境完成代码和测试, 之后用生产环境生成代码,执行npm run build 命令后，会生成dist目录，里边包含index.html和static文件夹。

npm run build的时候, 一开始就会提示Built files are meant to be served over an HTTP server. Opening index.html over file:// won't work.

在vue-cli的默认配置中, 把assetsPublicPath: '/'改成assetsPublicPath: './',dist文件夹里的文件必须放在服务器的根目录

如果你想本地打开的话, 可以在npm run build完成之后执行以下命令:npm install -g http-server // 该命令只需执行一次, 安装过之后, 以后就不需要重复安装了

build: {
    // Template for index.html
    index: path.resolve(__dirname, '../dist/index.html'),
    // Paths
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: './',       // 修改此处
}
