#概要
初投稿です。

こちらの動画を見ながら環境構築をしていた最中に
docker-compose build
docker-compose up を実行したら

Could not find gem ‘mysql2 (>= 0.4.4, < 0.6.0)’ in any of the gem sources listed in your Gemfile.
というエラーが出た。

#開発環境
macOS catalina
バージョン10.15.7

#試したこと
とりあえずググって

  • myslqの再インストール
  • ruby2.5.8から2.6.6へのアップデート
  • docker desktopの再設定

その他諸々のことを試したが色々試したが事象変わらず。
4時間経過。
朝日が登ってきて泣きそうになる。

#解決方法

docker-compose run web bundle install
docker-compose up
の順で実行したら解決した。
