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
