warning: no previously-included files matching '*.pyc' found anywhere in distributionについて

Question

pipでインストールする際に、
warning: no previously-included files matching '*.pyc' found anywhere in distributionという警告メッセージが出力されたのですが、
これはどういう意味なのでしょうか。

原文）
warning: no previously-included files matching '*.pyc' found anywhere in distribution

意味）
警告: あらかじめ同梱した*.pycに一致するファイルが、頒布品のどこにも見当たりません。

起きていること)
同じような件が、numpyのインストールなどであった、というような検索結果がちらほら見られますね。たぶん、インストールに必要なモジュールが古かったりまるで入っていなかったりで使えなかったことに対する警告だと思います。今回の場合、zope.interfaceというのがなかったために警告が出て、途中で自動でインストールされたようですね。

ありがとうございます。

インストールに必要なモジュールがなかったので、自動でモジュールをインストールしたとのことで、承知致しました。
