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

Lösung (funktioniert zumindest bei mir): (ryu)Macbook:ryu Benny$ STATIC_DEPS=true pip install lxml Downloading/unpacking lxml

….

pip install ryu ← funktioniert dann

Um an die Beispiele zu kommen:
