This one will solve all your problems not only for Mac but works on every basic shell - gt  Linux also  If you have a Mac and you ve installed python3 like most of us do     with brew install - ofc  your file is located in   usr local Cellar python 3 6 4 4 bin python3  How do you know  - gt  you can run this on every basic shell Run  which python3  You should get   usr local bin python3  Now this is a symbolic link  how do you know  Run  ls -al  usr local bin python3   and you ll get   usr local bin python3 - gt   usr local Cellar python 3 6 4 4 bin python3  which means that your  usr local bin python3   is actually pointing to   usr local Cellar python 3 6 4 4 bin python3  If  for some reason  your  usr local bin python3   is not pointing to the place you want  which in our case   usr local Cellar python 3 6 4 4 bin python3  just backup it  cp  usr local bin python3   orig    and run  rm -rf  usr local bin python3  now create a new symbolic link  ln -s  usr local Cellar python 3 6 4 4 bin python3  usr local bin python3   and now your  usr local bin python3  is pointing to  usr local Cellar python 3 6 4 4 bin python3   Check it out by running  ls -al  usr local bin python3

GCC 4 2 1  Apple Inc  build 5646   is the version of GCC that the Python s  were built with  not the version of Python itself   That information should be on the previous line   For example     Apple-supplied Python 2 6 in OS X 10 6    usr bin python Python 2 6 1  r261 67515  Jun 24 2010  21 47 49    GCC 4 2 1  Apple Inc  build 5646   on darwin Type  help    copyright    credits  or  license  for more information   gt  gt  gt      python org Python 2 7 2  also built with newer gcc     usr local bin python Python 2 7 2  v2 7 2 8527427914a2  Jun 11 2011  15 22 34    GCC 4 2 1  Apple Inc  build 5666   dot 3   on darwin Type  help    copyright    credits  or  license  for more information   gt  gt  gt    Items in  usr bin should always be or link to files supplied by Apple in OS X  unless someone has been ill-advisedly changing things there   To see exactly where the  usr local bin python is linked to     ls -l  usr local bin python lrwxr-xr-x  1 root  wheel  68 Jul  5 10 05  usr local bin python  - gt           Library Frameworks Python framework Versions 2 7 bin python   In this case  that is typical for a python org installed Python instance or it could be one built from source
