実現したいこと
ruby on railsのプロジェクトを作成しまして、 bundle installした際にエラーが発生しました。
mysql2に関するエラーでした。
検索して、bundle installからmysqlをインストールしようとしたりしたのですが、失敗しました。
mysql2を入れる方法はありますか？

Your Gemfile lists the gem rails-i18n (>= 0) more than once. You should probably keep only one of them. Remove any duplicate entries and specify the gem only once. While it's not a problem now, it could cause errors if you change the version of one of them later. Fetching gem metadata from https://rubygems.org/..........
