RVMがそのようなファイルを読み込めない - win32/resolv（LoadError）

Question

RVMを使ってruby 2.2.3をインストールしました。それは正常にインストールされ、私は宝石がレール（またはそのことについては、宝石を）インストールを実行するとき、それは私に、このエラーを与える：

私は、Windows 10 Proは、Cygwinの、RVM 1.27.0を使用しています。 RVMのgithub（https://github.com/rvm/rvm/issues/3519）には、私が得ているものとかなり似ている古い問題がありましたが、答えは見つかりませんでした。

この問題の修正は、libffi-develもインストールしてから、rubyを再インストールすることです。そうすれば、fiddle/win32のような必要な宝石はすべて適切にインストールされます。

私はちょうど同じプロセスに続き、それも新しいR​​ubyのバージョンで私のためにそれを固定：私はRailsInstallerが何と比較したとき、私はそれは、Win32のような標準ライブラリの多くが欠けていることに気付く2.3.1
