Vue — px转rem

1.下载lib-flexible

npm i lib-flexible --save

2.引入lib-flexible 在main.js中引入lib-flexible

import 'lib-flexible/flexible'

3.安装px2rem-loader

npm install px2rem-loader

4.配置px2rem-loader 在build文件中找到util.js，将px2rem-loader添加到cssLoaders中，如：

  const cssLoader = {
    loader: 'css-loader',
    options: {
      minimize: process.env.NODE_ENV === 'production',
      sourceMap: options.sourceMap
    }
  }
  const px2remLoader = {
    loader: 'px2rem-loader',
    options: {
      remUnit: 75
    }
  }

同时，在generateLoaders方法中添加px2remLoader

function generateLoaders (loader, loaderOptions) {
    const loaders = [cssLoader,px2remLoader]
    if (loader) {
      loaders.push({
        loader: loader + '-loader',
        options: Object.assign({}, loaderOptions, {
          sourceMap: options.sourceMap
        })
      })
    }
}
