Yes, it'll install P圓 all over again, but unless you're really starving for disk space (in which case you probably don't want to be installing large packages like IPython) it's no big deal. My personal favorite is to install Python 3 and IPython using MacPorts. By default, the Anaconda installer gives you Python 2.7, but you can use the conda command to install Python 3.

You can install Anaconda, a ' Completely free enterprise-ready Python distribution for large-scale data processing, predictive analytics, and scientific computing' with over 100 packages, including IPython and its dependencies. IPython is large and quite complex, with many moving parts, so in the absence of a package manager (see below) it can take a bit of time before everything is up and running. Make sure you read the docs before you start, so you have an idea of what you're trying to achieve. If installation chokes, use pip3 to install pyzmq, tornado, pyreadline, jinja2, pygments, and maybe a few others. You should now be able to run sudo pip3 install ipythonĪnd hopefully all the dependencies will be installed as well. Navigate there in Terminal, and run sudo python3 get-pip.pyĪnd you should soon have either a pip3 or pip-3.3 command (maybe both, I don't remember).

Briefly, download get-pip.py and save it someplace, like your Downloads folder. You need to install pip for Python 3 - it's as easy as going to the Installation page and following the instructions.
