ドルヲタ系インフラエンジニア じーふーの備忘録

クラウドをメインに扱うインフラエンジニアが書くメモやら雑感、たまにドルヲタ的活動記録残します。最近の推しはAzureのData Factory(V2)です。

【Python / Ansible】 Ansible実行時、pycryptoのバージョンによりAttributeError

python ansible

pycrypto(バージョン2.4以上)をインストールしている状態でansibleを実行すると、下記エラーが出るみたい？
pycrypto 2.3 をインストールすると正常に動作することを確認し、2.4、2.6.1(執筆時点での最新バージョン)インストール状態で動作確認した際はエラーとなりました。

[vagrant@vagrant-centos65 ~]$ ansible all -i 'localhost,' -c local -m ping

追記(2015/04/30)

下記issue内にてエラー発生源の処理をコメントアウトする方法で対応した方もいましたので、そちらも紹介致します。
※紹介先サイトで対応した方も、正しい対応かはわからないけど...と言っていますので、こちらの対応が正かどうかは自信ありません。申し訳ございません
下記対応を入れた状態で、pycryptoのバージョンを2.4以上のものにアップデートして、正常に動作することを確認しました。
