brew install mysql
Warning: mysql 8.0.11 is already installed and up-to-date
To reinstall 8.0.11, run `brew reinstall mysql`
その後
gem install mysql2

You can try again using `brew postinstall mysql`
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
==> Summary

紛らわしく、正直なところ、私は100％を理解しておらず、問題の根源である可能性が非常に高いですが、わかりません。

私はそれが私を夢中にさせているので、私はそれに着くことができるどんなアドバイスも大好きです。より良い質問をするために提供できる他の情報を教えてください。
前もって感謝します
今日、この問題に遭遇しました。 mysqlは最近更新されたので、私のために働いたのは：
brew install [email protected]
brew link [email protected] --force
bundle install
別の方法として、私はこの解決策を試しませんでしたが、他の人々のために働いたようです。
Mac Proにmysql2-0.3.21をインストールするときに同じ問題に直面しました。
下記のソリューションは私のために働いた（プロジェクトフォルダを指しているターミナルで下記の3つのコマンドを実行する）：
brew install mysql
gem install mysql2 -v '0.3.21' -- --srcdir=/usr/local/mysql/include
bundle install
MacBook ProのMacOS Mojaveへのアップグレード中にディスクがクラッシュしたため（きれいではありません！）、その後、すべてのコードプロジェクトを再構築する必要がありました。
特定のプロジェクトの立ち上げと実行が非常に困難であることが判明したため、今日、古いRoRプロジェクトでmysql2-0.3.21を実行する方法を探して数時間を費やしました。 Rubyバージョン2.1.1p76 with Rails 4.1.1。
最後に、このアドバイスに従うことで成功しました： https://github.com/brianmario/mysql2/issues/1010#issuecomment-460257986
次の手順を実行しました。
まず、gemsetからmysql2のインストール済みバージョンをすべて削除します。
gem uninstall mysql2次に、MySQL 5.6をインストールします。MySQL8.0.17が既にインストールされているため、5.6は樽としてのみインストールされます。
brew install [email protected]次に、次のコマンドを使用してmysql2バージョン0.3.21をインストールします。
gem install mysql2 -v 0.3.21 -- --with-mysql-config=/usr/local/Cellar/[email protected]/5.6.42/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
OpenSSL部分はおそらく省略でき、プロジェクトの実行中のRailsのバージョンに応じてmysql2のバージョン番号を変更できます。
上記のステップの後、Railsコンソールを再び開始し、データベースを照会できました。
Loading development environment (Rails 4.1.1)
2.1.1 :001 > User.count
(18.7ms) SELECT COUNT(*) FROM `users` WHERE `users`.`deleted_at` IS NULL
=> 1222
2.1.1 :002 >
これは私のために働いた-macOS Catalina
brew uninstall mysql
gem uninstall mysql2
brew install [email protected]
brew link [email protected] --force
gem install mysql2 -v '0.3.21'
# Gemfile
gem 'mysql2', '0.3.21'
bundle update mysql2
