+Installing and setting up Python 3 as default
|
|
|
+---------------------------------------------
|
|
|
+
|
|
|
+Basing on macOS `Catalina 10.15 release notes`_, use of Python 2.7 is not recommended and Python will not be included by default in future versions of macOS. Check what Python you currently have::
|
|
|
+
|
|
|
+ python --version
|
|
|
+
|
|
|
+If the output is like ``Python 2.7.17``, your default interpreter is Python 2.7. If so, also check if Python 3 isn't already installed on your computer::
|
|
|
+
|
|
|
+ python3 --version
|
|
|
+
|
|
|
+If above command returns an error, it means Python 3 is not installed.
|
|
|
+
|
|
|
+Below is an overview of steps to install Python 3 and making it default interpreter.
|
|
|
+
|
|
|
+ - Installing with HomeBrew_ can be done as follows::
|
|
|
+
|
|
|
+ brew install python3
|
|
|
+ ln -s /usr/local/bin/python3.8 /usr/local/bin/python
|
|
|
+
|
|
|
+ Adjust above directory name ``/usr/local/bin/python3.8`` to point where Python 3 has been installed. To check this directory you can run ``which -a python``.
|
|
|
+
|
|
|
+ - If you have MacPorts_, you can run::
|
|
|
+
|
|
|
+ sudo port install python38
|
|
|
+ sudo port select --set python python38
|
|
|
+
|
|
|
+Now open a new terminal session to verify what python is running by default::
|
|
|
+
|
|
|
+ python --version
|
|
|
+
|
|
|
+If the output is similar to ``Python 3.8.5``, your installation has been done successfully.
|
|
|
+
|
|
|

|
|
|
+.. note::
|
|
|
+
|
|
|
+ This is system-wide change which may affect all of the applications.
