不能使用任何Laravel命令？爲什麼是這樣？

Question

我已經安裝了Laravel和需求的需求，因爲我希望將它用於理想的論文。

在嘗試運行任何命令時，我似乎遇到了這個問題，而且無論如何都會顯示此錯誤。

PHP Warning: require(/var/www/assignment/bootstrap/../vendor/autoload.php): failed 

to open stream: No such file or directory in /var/www/assignment/bootstrap/autoload.php on line 17 PHP Stack trace: PHP 1. {main}() /var/www/assignment/artisan:0 PHP 2. require() /var/www/assignment/artisan:16 PHP Fatal error: require(): Failed opening required '/var/www/assignment/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/assignment/bootstrap/autoload.php on line 17 PHP Stack trace: PHP 1. {main}() /var/www/assignment/artisan:0 PHP 2. require() /var/www/assignment/artisan:16

對不起，如果格式不正確那裏。

composer update
