vue项目使用webpack loader把px转换为rem

下载lib-flexible

https://github.com/amfe/lib-flexible

npm i lib-flexible --save

在main.js中引入lib-flexible

import 'lib-flexible/flexible'

安装px2rem-loader

https://github.com/songsiqi/px2rem 配置px2rem-loader 在build文件中找到util.js，添加px2rem-loader到cssLoaders中

  const px2remLoader = {
    loader: 'px2rem-loader',
    options: {
      remUnit: 75
    }
  }

更改generateLoaders函数

  function generateLoaders (loader, loaderOptions) {
    const loaders = [cssLoader, px2remLoader,postcssLoader]    //添加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)
    }
  }

完成之后重启

npm run dev
