window 怎么办？

不懂，大神，有没有QQ在线的，我截图给您看

全部执行了 composer update 和composer install 还以为是扩展没打开，extension=php_mbstring.dll全开打了

vendor文件夹不存在，但是我用laravel new laravel就能出现vendor文件夹，用laravel new laravle5.5 --dev就没有vendor文件夹

新手，求大神们解决下

test (2).html:19 Uncaught ReferenceError: setTimeOut is not defined
for(var i=0;i<10;i++) {

    console.log(i);
    setTimeOut(function(){
        console.log('i:${i}');
    },1000)
