私は、Xcodeのインストールされたアプリケーション（つまり、理にかなっているかどうかわからない）持っている私はダウンロードして更新しました自作

私は「崇高」のテキストエディタを使用してそれを開いエラーが

/Users/ravi/.rvm/gems/ruby-2.4.0/gems/pkg-config-1.2.4/lib/pkg-config.rb:299:in `parse_pc': .pc for zlib doesn't exist. 

だと思います。 しかし、これを修正する方法がわかりません。助けてください。

さらに詳しく：私はRuby 2.4を使用していますが、OS X Yosemiteバージョン10.10.5があります。
