Drushエラー： "ContainerAwareEventDispatcher"はEventDispatcherInterface :: getListenerPriorityを実装していません
私はDrupal 8.1.2およびDrush 8.1.2（OS X 10.11.5、PHP 5.6.19）を使用しています）
すべてのdrush-commandsで、symfonyの実装が欠落しているというエラーが発生しますEventDispatcherInterface::getListenerPriority drupalコア。
エラーは、クリーンdrupalインストールおよび更新時に発生します。別のdrupal-version（古いバージョンと最新の-> 8.1.2）と古いdrush-をインストールして問題を解決しようとしましたバージョン（composer、8.1.0を使用）、ただし結果なし。
これは私のスタックトレースです：
localhost:web3 myusername$ drush up

このエラーはドラッシュに関連していると確信しています。私は何を見逃していますか？
グローバルにインストールされたDrushではなく、サイトローカルのDrushを使用してみてください。
