Rubyの霧の宝石が原因でサーバーが動作しない：そのようなファイルを読み込めません - xmlrpc/client（LoadError）

Question

タイトルとして、私はレールアプリを扱うためのUbuntu 16.04システムを設定しようとしています。霧の宝石をコメントアウトすると、サーバーがローカルで起動し、そこに残っている宝石が次のエラーメッセージを生成します。 Googleと同じエラーで他の誰かを見つけることができないため、グーグルリングは何も提供していないようで、必要なときにアプリケーションから宝石を単に取り除くことはできません。

完全なメッセージは以下の通りです：

誰がどのようXMLRPCクライアントや仕事が認識されるであろう問題を中心にダウンロード/インストールする方法のいずれかを私に伝えることができます。

Answer 1

Ruby 2.4.0以降では、rubyにバンドルされていたxmlrpcライブラリがgemに抽出されてしまうという問題があります。だから、これをあなたのgemファイルに追加し、再度バンドルする必要があります。

gem 'xmlrpc'
