VUE手机端使用rem

注：若要使用sass，先配置rem
安装px2rem

npm install px2rem-loader  lib-flexible --save 

在项目入口文件main.js中引入lib-flexible

import 'lib-flexible/flexible.js'

在build下的 utils.js中，找到generateLoaders 方法，在这里添加

  const px2remLoader = {
    loader: 'px2rem-loader',
    options: {
      remUnit:37.5
    }
  }

  // generate loader string to be used with extract text plugin
  function generateLoaders (loader, loaderOptions) {
    const loaders = options.usePostCSS ? [cssLoader, postcssLoader, px2remLoader] : [cssLoader, px2remLoader]

    if (loader) {
      loaders.push({
        loader: loader + '-loader',
        options: Object.assign({}, loaderOptions, {
          sourceMap: options.sourceMap
        })
      })
    }

    // Extract CSS when that option is specified
    // (which is the case during production build)
    if (options.extract) {
      return ExtractTextPlugin.extract({
        use: loaders,
        fallback: 'vue-style-loader'
      })
    } else {
      return ['vue-style-loader'].concat(loaders)
    }
  }
