載せてあるエラーメッセージの最後に log の場所が書かれています。
これを読むとエラーの原因と 対策のヒント がかかれていると思います。最後の方。
たいていなんかのfileが足りないので取り寄せる ということになります。
ただ、
生のWindowsで build gem native extension. は厄介かも。今後こういうのが続々でてくるかと。
この問題解決のための手順でも出てくるかも。
今回のエラー対応方針を建てることが自力でできなかったのですから、それをクリアできるかどうか。
なんのためにrubyでの開発をやっているのか、によりますが 勉強のためであるなら 仮想環境でLinuxを動かしてそこでやることを薦めます
