発生した背景
久々に自分で作成したアプリケーションを起動しようとすると、以下のエラーが出力されて、アプリが起動されません。対応した手順を記録します。
（バージョンが合わないなどの問題もありましたが、こちらは別記事にしようと思います。）
非常に長いエラーのため、慎重に対応していく
再現手順/実行した内容
アプリのrootpathで、rails -s」コマンド実行した際に、出力されたエラーです。

対応方法
エラーの出力量が非常に多いため、環境を再構築する方が早いかもしれないと考えたが、時間を決めて対応してみることに。
- ①記述に従い、「gem pristine nokogiri --version 1.10.1」を実行してみる。
- bundle execを付加して実行してみる。
- bundle install --path vendorの実行
- 結果 -> 同じエラーが出力される。
- ②背景から一度「bundle update」を実行してみる。
- 結果 -> エラー２だけが出力されるようになった
背景として他のアプリを起動するため、homebrewコマンドでインストールを実施した際に、途中で失敗。これに伴い、osのリカバリを実施したのち、XcodeなどRailsが関係するアプリケーションを再設定した。
エラー１が解消したのは、これらの操作によってGem環境も×になったため、「bundle install」で解消したものと想定する
エラー２の対応方法については別記事にて掲載する。
