ruby - Windows 8 x64 での ffi の問題

Question

最初に berkshelf gem を使用しようとしましたが、

次に、異なるバージョンで ffi gem を再インストールしようとしました

gem uninstall ffi
gem install ffi -v 1.0.9

gem uninstall ffi
gem install ffi

うまくインストールできますが、ドキュメントのインストール中に何かが失敗します

gem uninstall ffi
gem install ffi

しかし、ffi をインストールしても berkshelf の主な問題は解決されませんでした。

64 ビット Linux で別の gem をインストールする際にも同様の問題がありました。gem をコンパイルすると、ffi gem に関してまったく同じエラーが発生します。私の修正は libffi-dev パッケージをインストールすることで、うまくいきました。このパッケージの Windows/MingW バージョン用の X86-64 があるので、これがインストールされていることを確認することをお勧めします。

ruby バージョン 1.9.3 ruby 1.9.3p551 および 64 ビット Linux でも同様の問題が発生しました。回答番号 1 のように、libffi-dev のインストールが最初のステップでした。

gem uninstall ffi
gem install ffi

まだ同じ問題がありました。rdoc gem のインストールを追加した後でのみ:

gem install rdoc
gem uninstall ffi
gem install ffi

エラーなしで動作しました。
