composer系コマンドの実行進捗を逐一表示するオプションを紹介する。

紹介

composer系コマンドにオプション-vvvを付与して実行する。

例

laravelプロジェクトの作成時などcomposerコマンドを実行するとかなり時間がかかり「止まっているのでは？？」と思うことがある。
下記のよう-vvvを付けて実行することによりより細かいダウンロード処理などの進捗をターミナルに表示してくれるようになる。
- laravel8_testというプロジェクトを新たに用意する時のコマンドを下記に記載する。
```
$ composer create-project "laravel/laravel=8.*" laravel8_test -vvv
```

そうすると下記の様に細かく進捗が表示される。
