Answer 1

尝试从命令行运行

composer install 
or composer update

Answer 2

作曲家更新

您只需要运行composer update来更新您在此文件composer.json中指定的依赖项。该命令也会生成vendor/autoload.php。

  

Laravel documentation

     

Laravel利用Composer来管理其依赖项。首先，下载composer.phar的副本。拥有PHAR归档文件后，可以将其保存在本地项目目录中，也可以移至usr/local/bin以在系统上全局使用它。

     

在Windows上，您可以使用Composer Windows installer。
