用postcss给less加上webkit前缀

const autoprefixer = require('autoprefixer')
const postcss = require('postcss')
const fs = require('fs')
const syntax = require('postcss-less');

var sprites = require('postcss-sprites');
var opts = {
    stylesheetPath: './dist',
    spritePath: './dist/images/'
};

//给less加上webkit前缀
const lessText=fs.readFileSync('./app.less');
postcss([ sprites(opts),autoprefixer])
    .process(lessText, { syntax: syntax })
    .then(result => {
        console.log(result)
       console.log(result.content);
    })
