Right now this can be accomplished by creating two Anaconda installs, say in "anaconda2" and "anaconda3" directories, and adding both "bin" subdirectories to the path. But this leads to a lot of unnecessary, duplicate packages installed in both hierarchies.

As a "wishlist" feature request, it would be nice to be able to create both a Python 2 and 3 install (in "anaconda/bin", etc.) from running the Anaconda installer. This would allow system scripts to run with either Python 2 or 3. All the relevant Python executables, etc.

The easiest way to do this is to create two conda environments, one for each Python, and put them both in your PATH (put the one that you want the unversioned python to point to first). You never need to install anaconda more than once. Use conda environments, like conda create -n py3k python=3.4 anaconda.
asmeurer commented on Aug 22, 2014
Also note that the packages are duplicated no matter what, because Python 2 and Python 3 store things in different locations ( lib/python2.7 and lib/python3.4 ). Conda uses hard-links to install packages into different environments, so installing the same package into two environments does not use any additional hard disk space.

Sorry to reopen this, but can I have both a Python 2.7 python and a python 3.x python3 executable available in one Anaconda environment? I am using Anaconda for my default python for my user, but run into problems now because then some programs cannot find the system python3 executable.

This is also a wish list item: But To this poster's point: if you are trying to learn Python or Data Science concepts, some classes now use Python 2.7.x and others use 3.x (3.5 ... 3.6 ...). A novice user can get into real trouble trying to solve problems like how to make Spyder switchable between two environments.

Hi, I kept having the same issue every time I tried to install Anaconda 64 bit. I installed and uninstalled it multiple times and choose the different settings hoping to solve the problem. Finally, I decided to try and install the 32 bit instead and it worked, I got no connectivity issues and all installed perfectly.
