macos 10.15.7 How to remove python 2.6

I am attempting to install PlatformIO on a iMac 2019 macos 10.15.7 but I get the following error: OSError: [Errno 86] Bad CPU type in executable: '/Library/Frameworks/Python.framework/Versions/2.6/bin/python'

I get the same error if I enter python2.6 in to a terminal window.

I am sure that python 2.6 is 32 bit and Catalina is 64 bit.

From a terminal echo $PATH gives the following :

/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.8/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/2.6/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:/opt/X11/bin:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands

I am unable to find any instructions for removing python 2.6, do you know of any? Could I just change the PATH statement if so how? Can I just delete the /Library/Frameworks/Python.framework/Versions/2.6 directory ?

iMac 27″, 10.13

Thank you again VikingOSX, the problem is now fixed and PlatformIO is now installed. Whilst trying to find how to permantly change the PATH statements I cam across a method for the Zsh shell. I then noticed a prompt on my terminal window to change to the Zsh by entering "chsh -s /bin/zsh". I did this and the tried the echo $PATH I now get /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:/opt/X11/bin:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands

All duplicates have gone and PlatformIO installs.

Thank you again for your help

The default System Python that you access in Catalina (or Big Sur) is v2.7.16. The default Python3 that you access is v3.9.0 (due to your PATH setting). Ignore removing Python 2.6.

You need one entry in your PATH statement and you have redundancies:

export PATH="$HOME:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.9/bin:$PATH"

VikingOSx, thank you for your quick response, my question now if I use the export command in your reple will this apply across all of my computer or just the terminal window? and should I add in the other entries such as /opt/local/bin:/opt/local/sbin:

Dec 1, 2020 2:39 AM in response to Jasea

The export command will apply only to your future Terminal usage. There is no /opt path on my M1 mini running 11.0.1, so I cannot offer advice on those additions to your PATH.

The current version of PlatformIO requires Python 3.5 or later, and they do not recommend any Python 2.7.* as it is now deprecated by Python.org.

You are welcome.
