#概要
https://www.youtube.com/watch?v=plDBsStXuO4&list=PLCyDm9NTxdhLnA4tH5ToQR1K1LcWIAdOa&index=3

こちらの動画を参考にしてLaravelアプリを作成する過程で以下のエラーが発生したので解決するまでにしたことを記しました。

#実施環境
#####ハードウェア環境

項目 情報
OS MacOS Big Sur (11.5.2)
ハードウェア MacBook Pro (Retina, 13-inch, Late 2013)
プロセッサ 2.4 GHz デュアルコアIntel Core i5
メモリ 4 GB 1600 MHz DDR3
#####ソフトウェア環境
項目 備考
:-: :-:
MAMP (v6.6) 無料版
Laravel (v8.6.5)
Composer (v2.1.9) homebrewでインストール

#問題発生まで

こちらの動画及び

こちらの動画の6:30までと同じことを行いました。
MAMPやLaravel、Composerは、私が使用しているものと動画で使用されているものとでバージョン差があります。

#問題

＃02の動画の6:30にあるように下記のコマンドを実行してマイグレーションファイルを作成しようとしたところ

$ php artisan make:migration create_blogs_table

下記のエラーが発生しました。

Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.0.0". You are running 7.3.24-(to be removed in future macOS). in /Applications/MAMP/htdocs/blog/vendor/composer/platform_check.php on line 24

#結論
下記のコマンドを実行するとうまくいきました

$ composer update
$ composer install --ignore-platform-reqs

Composerが最新になっていなかったため、PHPのバージョンチェックを無視するコマンドが機能していなかったと思われます

#解決するまでにやったこと　
※長いです
