virtualenv がどのように機能するのかよくわからないかもしれませんが、--always-copy フラグを指定して virtualenv を実行すると、/lib/python 内のすべてのファイルがコピーされることを期待しています。
だから私は仮想環境を作成します
virtualenv -v --always-copy myenv
その出力は

正確には、ディレクトリを含めて50ですが、pythonインストールディレクトリのファイル/ディレクトリを数えると200以上になります(サイトパッケージなどを数えずに1レベルだけ)
なぜこれがこの動作なのか、誰かが知っていますか?
さえ__future__.py
ありません。
