Python 2.7 'packaging'パッケージが必要です。通常これはこのパッケージにバンドルされています

Question

これは暗号化モジュールと関係がありますが、わかりません。

Traceback (most recent call last):

ImportError: The 'packaging' package is required; normally this is bundled with 
this package so if you get this warning, consult the packager of your distributi 
on.

私はcryptography.hazmat.bindings._padding.pydという名前のファイルに気づいた、と私は人々がそれで問題が発生したどこかで見ました。フックや何かを編集する必要はありますか？
