Ways to run Python

OSX

  • default configuration (python2.7):
/usr/bin/python 

is normally going to run python2.7, linked like this /usr/bin/python2.7@ → ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 when using this native version of python, some dependences might run into permission problems and thus installing modules via pip requires an extra flag “–user” which installs it only for the current users

  • pyhton3: osx comes with python3 installed, which can be called with
$ python3 
  • conda is a package and environment management system for Python, R, Node.js, Java and other application stacks. It creates an environment (-n name) using a specified python version
conda create -n myenv python=3.4

On managing (python) environments with conda: https://conda.io/docs/user-guide/tasks/manage-environments.html

  • virualenv is a python module installed using
pip install --user virtualenv
virtualenv --python python3 env
source env/bin/activate
