修改vue+webpack run build的路径方法

vue项目用webpack打包想要修改静态资源路径等,找到项目根目录下的config文件夹，打开该文件夹下的index.js文件，默认如下：

// see http://vuejs-templates.github.io/webpack for documentation.
var path = require('path')

module.exports = {
build: {
env: require('./prod.env'),
index: path.resolve(__dirname, '../dist/index.html'),
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
assetsPublicPath: '/',
productionSourceMap: true,
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
},
dev: {
env: require('./dev.env'),
port: 8080,
autoOpenBrowser: true,
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {},
// CSS Sourcemaps off by default because relative paths are "buggy"
// with this option, according to the CSS-Loader README
// (https://github.com/webpack/css-loader#sourcemaps)
// In our experience, they generally work as expected,
// just be aware of this issue when enabling this option.
cssSourceMap: false
}
}

其中build.index：必须是本地文件系统上的绝对路径。会生成index.html文件。

build.assetsRoot：必须是本地文件系统上的绝对路径。

build.assetsSubDirectory：编译出来的资源文件。

build.assetsPublicPath：【资源的根目录】，这是通过http服务器运行的url路径。默认情况下，是根目录(/)。如果后台对静态资源url前缀要求，则需要改变这个路径。

build.productionSourceMap：在构建生产环境版本时是否开启source map。
