Rails を新しくインストールしましたが、コンソールまたは任意の rake タスクを実行しようとすると、次のようなエラー メッセージが表示されます。

これを引き起こしている可能性のあるアイデアはありますか？

リードラインだと思います

/.rvm/rubies/ruby-1.9.2-p320/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load --readline (LoadError)

以下にいくつかのリソースを示します。

Rails コンソール、RVM、および readline に関する問題

上記がうまくいかない場合は、私が行ったことを実行して、ここで解決策を使用できます。

Rails3 と readline の問題

これは、プロジェクトに rb-readline gem を含めることです。（これがハッキングと見なされるかどうかはわかりません）

https://github.com/luislavena/rb-readline

それが役立つことを願っています。コンソールを一度動作させるのにしばらく時間がかかり、時にはイライラする以上のものでした. 言うまでもなく、いくつかのUbuntuパッケージを更新した後、もう一度やり直さなければなりませんでした。
