だから、私はRails（そして必要なgem）を正しくインストールするために一日の大部分を費やしました。
ラインキャッシュとnokogiriを何時間も使用した後、私は疲れ果てたと感じ始めており、「pg」ジェムのインストールで問題が発生しました。
私は戦い続けるつもりですが、この問題についてここで何かアドバイスはありますか？
（1つのSO投稿で2つの質問をするべきではないことはわかっていますが、とにかく行きます。過去に大量のソフトウェアをインストールしたことがあり（Linuxカーネルを最初からコンパイルすることを含む）、Railsをインストールするのは非常に難しいようです。 Snow Leopard。古き良き時代にLinuxディスプレイドライバを動作させるのと同じくらいです。このプロセスをより簡単にするためにどこかで進歩はありますか？）
エラーログは次のとおりです。
