vue-cli ui 里的依赖最新版本列表怎么来的？

const spawn = require('cross-spawn');
var result = spawn.sync('npm', ['view', 'react', 'version']);
console.log("result: " + result.output[1].toString( 'utf-8', 0, result.output[1].length ));

const rp = require('request-promise');
const plugins = require('./plugin');
let start = +new Date();
console.log(plugins.length);
const getLatestVersion = async() => {
    let latestArr = [];
    for(var i = 0; i < 10; i++) {
        var url = 'https://registry.npmjs.org//' + plugins[i];
        result = await rp(url);
        if(result) {
            let obj = JSON.parse(result) || {};
            let lastVersion = JSON.parse(result)['dist-tags']['latest']
            latestArr.push(result);
        }
    }
    return latestArr
}

getLatestVersion().then(data => {
    let end = +new Date();
    console.log('处理结果是：' + data);
    console.log('处理这些请求一共花了：' + (end - start) / 1000 + '秒');
})

var plugin = [
