##試した事
mkdir ~/Library/LaunchAgents
ln -sfv /usr/local/opt/mysql@5.6/*.plist ~/Library/LaunchAgents
こちらの二つのコマンドを打つと、一応アプリ作成は行えるが、また別のアプリ作成時に同様のエラーが発生する。
##自身の考察
3週間ほどPHPの学習もしており、その際に何かしらのパスの編集をしてしまった?
その間にmysqlのアップデートがあったのかrailsを使っている友人にmysqlでのエラーが発生していた.
##終わりに
rails初学者になります。
たりないもの等ございましたら指摘して頂けると幸いです。
よろしくお願いいたします.
追加現状 gem_make.out内
