vue webpack build资源相对路径的问题及解决方法

output: {
 publicPath: './',
 path: config.build.assetsRoot,
 filename: utils.assetsPath('js/[name].[chunkhash].js'),
 chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
 },

config文件夹下面的index
 build: {
 // Template for index.html
 index: path.resolve(__dirname, '../monitor01/index.html'),

 // Paths
 assetsRoot: path.resolve(__dirname, '../monitor01'),
 assetsSubDirectory: 'static',
 assetsPublicPath: './',
 ...
 }

 if (options.extract) {
 return ExtractTextPlugin.extract({
 use: loaders,
 fallback: 'vue-style-loader',
 publicPath: '../../'
 })
 } else {
 return ['vue-style-loader'].concat(loaders)
 }
