はじめに

お久しぶりです。
今回はStripeを実装しようとしたところ、バージョンが古いからアップデートしてくれ的なエラーメッセージが出たので、
Laravel5.6から5.8にバージョンをあげたときにやったことをメモ程度に書き残します。

以下メモ

composer.jsonを修正
laravel/frameworkを5.7に修正しcompoesr updateを実行。
エラーがなかったら5.8に修正しさらにcomposer updateを実行。

5.8にかえた段階でなんかエラーがたくさん発生

# 0 プロジェクト名/laravel/framework/src/Illuminate/Container/Container.php(785): NunoMaduro\Collision\Adapters\Laravel\CollisionServiceProvider->NunoMaduro\Collision\Adapters\Laravel\{closure}(Object(Illuminate\Foundation\Application), Array)
# 1 プロジェクト名/vendor/laravel/framework/src/Illuminate/Container/Container.php(667): Illuminate\Container\Container->build(Object(Closure))
# 2 プロジェクト名/vendor/laravel/framework/src/Illuminate/Container/Container.php(615): Illuminate\Container\Container->resolve('Illuminate\\Cont...', Array)
# 3 プロジェクト名/vendor/nunomaduro/collision/src/Adapters/Laravel/CollisionServiceProvider.php on line 44

とりあえずなんのことだか、さっぱりでしたが#3にヒントっぽいのがありましたので、そこのディレクトリまで移動して中身を確認。
多分ここでエラーが起きてます。。。
エラーの原因はわかったけど、修正の仕方がわからないので、適当にlaravel5.8のプロジェクトを作成しました。

CollisionServiceProvider.phpを修正しました。

とりあえずこの二つのファイルを修正しました。
php artisan を実行してみましょう。
動くはずです。

ざっと書きましたが上記の流れで自分はartisanが実行できるようになりました！
記事が少なくて大変でした。。。
