当我尝试访问我从github克隆的项目时，我得到了这个错误：
Warning: require(H:\xampp\htdocs\schedule.dev\bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in H:\xampp\htdocs\schedule.dev\bootstrap\autoload.php on line 17
Fatal error: require(): Failed opening required 'H:\xampp\htdocs\schedule.dev\bootstrap/../vendor/autoload.php' (include_path='H:\xampp\php\PEAR') in H:\xampp\htdocs\schedule.dev\bootstrap\autoload.php on line 17
我已经阅读了一些有同样问题的问题，所有人都说要运行
composer install
但是当我这样做时，我的命令提示符出错：
