- Link toInstalling the latest version of Python on Mac OS Catalina and overriding the old default pre-installed versionpodcast on anchorfm
I finally did it. I successfully installed Python version 3.7.7 viaHomebrew on my Maclaptop with OS Catalinainstalled.
Audioplayer is a cross platform Python 3 package for playing sounds (mp3, wav.). It provides the key features of an audio player, such as opening a media file, playing (loop/block), pausing, resuming, stopping, and setting the playback volume. In this video, I walk you through the process of installing Python 3 and properly setting it up so that it becomes the default instead of the System Python 2.
For those of you that still might be trying to figure outhow todo this, I will walk you through.
The reason why I was eager to make sure that I had the latest versioninstalled was because I am working on publishing (open-source)teaching-relateddocumentation on Read The Docs, and I need to havePythoninstalled in order to be able to install the programsnecessary to publishthere.
The default2.7.17 version of Python was retired this pastJanuary 2020. I had tried back then to replace it with Python 3+,but was unsuccessful at the time. The following is what I did today:
First I updated Homebrew. Yes, I used Homebrew to (re)installPython. It’s really easy. It’s just a matter of putting the pieces of thepuzzle together correctly!
It is recommended that you use pip = 8.0 together with setuptools = 0.8 to install gnureadline. This will download a binary wheel from PyPI if available, thereby bypassing the need for compilation and its slew of potential problems (especially on macOS). Use Python 3 as the macOS default. Python's website has a macOS Python 3 installer we can download and use. If we use the package installation, a python3 fill will be available in /usr/local/bin/. Aliasing is a must since the Python binary stored in /usr/bin/ can't be changed. What's nice about an alias is that it's specific to our command-line.
I ran the command
To updateHomebrew. Then I ran the command
To (re)install Python. Then I ran
To see which version of Python my Mac laptop was recognizing. Itstill recognized only Python 2.7.17. So I ran the followingcommand:
It told me the path to my newly installedPython 3.7.7. I had tochange the path to Python in order for my Mac to recognize thenewly installed version. This is what the command brew info python returned tome in Terminal:
So I had to add the following at the bottom of my .zshrc fileto update the path to my newly installed version of Python viaHomebrew:
Then I made sure to quitTerminal and go back in so that the pathwould actually be updated in a newTerminal windowinstance.
Then I checked what version of Python was recognized now with
And this is what was returned:
Macos Catalina Python3.8
Success! It’s as easy as that.
And BTW, if you don’t know how to access your .zshrc file in Catalina,you simply execute the following command:
Catalina Python3 Default
And your file will open in a new window. Then you can paste
At the bottom of the file.
I will be embedding this episode of Plugging in The Holes along with atranscript in the form of a post oninterglobalmedianetwork.com for yourhearing and reading pleasure. Bye for now!
