title: How to install 2 Anacondas (Python 2 and 3) on Mac OS
body: <p>I'm relatively new in Mac OS. I've just installed XCode (for c++ compiler) and Anaconda with the latest Python 3 (for myself). Now I'm wondering how to install properly second Anaconda (for work) with Python 2?</p>
  
  <p>I need both versions to work with iPython and Spyder IDE. Ideal way is to have totally separate Python environments. For example, I wish I could write like <code>conda install scikit-learn</code> for Python 3 environment and something like <code>conda2 install scikit-learn</code> for Python 2. </p>
