MacにDjango開発環境を構築する

先日、Ubuntu 16.4.1へのDjango開発環境の構築手順を説明しました。
Macでも作業をできるようしたいと思い調べていると、
Python Django入門 (2) Mac編 - Qiita
という詳細な環境構築手順ほか、Djangoチュートリアルを公開いただいているのを見つけました。

上記内容に従ってインストールをしてみたところ、virtualenvを入れるところでエラーに遭遇しました。
環境構築自体は今回割愛しますが、解決方法をメモしておきます。


この記事の実行環境は下記のとおりです。


sudo pip install virtualenv virtualenvwrapperを実行するとsixをインストールしようとしてエラーが発生。

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
