私はRubyにかなり慣れていないので、railstutorial.orgを調べているときに問題に遭遇しました。Ruby アプリケーションを「bundle install --without production」でバンドル インストールしようとすると、次のようになります。

An error occurred while installing pg (0.15.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.15.1'` succeeds before bundling.
次に、「gem install pg -v '0.15.1」を実行しようとすると、次のようになります。

今、私は立ち往生しており、問題を解決する方法がわかりません。同じ問題の範囲外の他の投稿を通じて多くの方法を試しましたが、何も機能していないようです. どんな助けでも大歓迎です！Yosemite を実行している Mac を使用しています。
これが私のGemfileです：
