Python 3 disappeared from computer - MacOS
use anaconda python distribution which better for python.
I am on OS Mojave and just used homebrew to install geos and proj and python3 disappeared. I had two versions and now I only have the 2.7 version. I did brew install python3 and it says its already installed but not linked, I then did brew link python as it suggested but it returned an Error: Could not symlink Frameworks/Python.framework/Headers Target /usr/local/Frameworks/Python.framework/Headers is a symlink belonging to python@2.. 
How can I go back to having both versions?. I am not 100% installing geos and proj was what caused it but I used python3 3 days ago.  I have also installed phantomjs via homebrew since the last time I used python3.
I need to have both versions of python installed. What would be the appropriate way of handling this since I seem to have all the files still on my computer?
Thanks in advance!
