Laravel 5 に Laravel-elfinder をインストールしようとしました。そのGitHub ページ には、従ったステップバイステップのチュートリアルがありますが、機能していません。
Windows 8 を搭載した Windows PC に XAMPP Web サーバーがあります。
基本的に、プロジェクトフォルダーに移動して実行します
composer require barryvdh/laravel-elfinder
数秒後、次のエラーが発生しました。
C:\xampp\htdocs\edent>composer require barryvdh/laravel-elfinder
Using version 0.3.* for barryvdh/laravel-elfinder
./composer.json has been updated
