Notizen: mkdir ryu

Ich empfehle „virtualenv“ zu verwenden. Dann noch „pip“ und „easy_install“ beschreiben. Beschreiben welches XCODE ich installiert habe (Command-Line Tools)

virtualenv ryu/

Macbook:Python Benny$ source ryu/bin/activate

1. Versuch der Installation (ryu)Macbook:ryu Benny$ pip install ryu Downloading/unpacking ryu
