cコンパイラがRubyのインストールを動作させない

Question

私はthisをインストールして複数のルビーバージョンをインストールしています。

私は数日前に以下のコマンドを実行するまで、私のCコンパイラは正常に動作しています。私は何をしようとしたのか覚えていない。私は数日前にGCCを台無しにしてしまったと思いますが、これは問題かもしれません。私が間違っていると思えば私を訂正してください。このコマンドは次のように言います：remove -r gcc temperory files。

注：このエラーは、1.8.7-p358バージョンをインストールしようとしている場合にのみ表示されます。私はCコンパイラが動作しているかどうかを確認するためにチェックrbenv

を使用してruby​​1.8.7-P358をインストールしようとすると、1.9.3-P125のためにそれだけで
