Hi

I've installed D8 by using git command in my local machine (in my laptop's hard) successfully and imported it to acquia dev desktop 2 in which gives a local site address (http://mynewsite.dd:8083) but when I chick on that URL, it unfortunately doesn't show the homepage and a page with below content is appeared:

Warning: require(C:\Users\Farhad\mynewsite/vendor/autoload.php): failed to open stream: No such file or directory in C:\Users\Farhad\mynewsite\autoload.php on line 14

Fatal error: require(): Failed opening required 'C:\Users\Farhad\mynewsite/vendor/autoload.php' (include_path='.;C:\Program Files\DevDesktop\common\pear') in C:\Users\Farhad\mynewsite\autoload.php on line 14

I deleted the first installation of D8 (using git) and reinstalled another one, that was installed well too but when I lunch it by acquia dev desktop the problem is still exist. please help my what to do. thank you
