Introduction

Mac OSX

Standard Python version 2.7.10 is installed on Mac OSX High Sierra and under MAMP. This version is located in:

  • /Application/MAMP/Library/bin/python
  • /usr/bin/python

Official this version is deprecated and is out-of-service from 2020. A good reason to upgrade [1]. The installer will create a directory:

  • /Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6
  • /usr/local/bin/python3.6

Python 2 installation

Python 2 is part of the software stack of the MAMP-installation.

The symbolic links in the Application MAMP bin directory (/Applications/MAMP/Library/bin): <syntaxhighlight lang="bash" line start="1"> $ la python* lrwxr-xr-x 1 frielink1 admin 7B Dec 23 20:01 python -> python2 lrwxr-xr-x 1 frielink1 admin 14B Mar 8 2016 python-config -> python2-config lrwxr-xr-x 1 frielink1 admin 9B Mar 8 2016 python2 -> python2.7 lrwxr-xr-x 1 frielink1 admin 16B Mar 8 2016 python2-config -> python2.7-config -rwxrwxr-x 1 frielink1 admin 2.0M Jul 6 2015 python2.7 -rwxrwxr-x 1 frielink1 admin 1.7K Jul 6 2015 python2.7-config </syntaxhighlight>

  • The 2st and 4rd' symbolic link make the python command point to python2.7 on the 6th line.
  • The 3nd and 5th symbolic link make the python-config command point to the python2.7-config on the 7th line.

python 3.7 installation

This version has been installed by the Mac user. It has the following symbolic links (/usr/local/bin): <syntaxhighlight lang="bash" line start="1"> $ la python* lrwxr-xr-x 1 root wheel 69B Dec 23 19:11 python3 -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3 lrwxr-xr-x 1 root wheel 72B Dec 23 19:11 python3-32 -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3-32 lrwxr-xr-x 1 root wheel 76B Dec 23 19:11 python3-config -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3-config lrwxr-xr-x 1 root wheel 71B Dec 23 19:11 python3.6 -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 lrwxr-xr-x 1 root wheel 74B Dec 23 19:11 python3.6-32 -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6-32 lrwxr-xr-x 1 root wheel 78B Dec 23 19:11 python3.6-config -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6-config lrwxr-xr-x 1 root wheel 72B Dec 23 19:11 python3.6m -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6m lrwxr-xr-x 1 root wheel 79B Dec 23 19:11 python3.6m-config -> ../../../Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6m-config </syntaxhighlight> There are 3 different Python version of 3.6 installed:

  • Python 3
  • Python 3.6
  • Python 3,6m

Migrate 2.7 to 3.6

First remove the python and python-config from the MAMP bin (/Applications/MAMP/Library/bin): <syntaxhighlight lang="bash" line start="1"> $ pwd /Applications/MAMP/Library/bin

$ mv python python_ $ mw python-config python-config_ </syntaxhighlight>

Now you can install Django. <syntaxhighlight lang="bash" line start="1"> $ pip install Django </syntaxhighlight>

If everything went alright, do: <syntaxhighlight lang="bash" line start="1"> $ $ python -m django --version 2.0

  1. Alternative
