Hi all
I need to update a Python package named Meson in order that I can compile an application.
I believe that I used the correction instructions but when I recheck the Python packages it still informs me that I am using the older build.
Also, I lost functionality of my OS and am unable to view my files, applications eg terminal refuse to open and my desktop changes colour.
The only way I can exit the OS is by powering down by the ON/OFF button.
What's going on??
@Jasper Do you have a backup of the save file/folder? For cases like this a roll back might be needed.
It sounds like something has crept in and is causing problems at the system level. I am guessing some systemd components are dependencies of one of the packages you've just installed/updated. If you can boot or get in and take a look at the directory /sbin in the save file/folder and compare it to the /sbin in the rootfs SFS.
This might not be exaactly the culprit but I believe it is along these lines that lib's changed or systemd components and/or configurations are present.

Thanks for replying and giving me some advice.
I do not think I installed systemd myself unless it is built in already. If not, then I will try to compile it and add it to my OS. Hopefully that will do the trick 
I generally do not make a backup of the my savefile as I have gone back from using a USB-HDD to a flashdrive. I messed up the initially setup on the HDD so found it easier to make changes to and from the flash drive.
In the past 48 hours I have only just begin to use @amethyst SFS toolkit as I did not completely understand it but realised that I could examine/repack SFS. Now I have realised how useful this can be.
I will try out the steps you outlined.
@Jasper Adding systemd to your Puppy Linux will break it in all kinds of ways! The trick is to see if a Puppy Linux needed symlink or configuration has been changed.
Sometimes I have had a save file/folder go bad for no reason that I could ever find the cause for and had to scrap it and start over.
@rockedge
Once I have time, I think I will download the packages into their default settings which appear to be
/usr/local (might be wrong???)
The existing files are located in a different location according to pFind.
I will copy over the downloaded and installed new files and then save them elsewhere.
Reboot and then copy them over and overwrite the existing files.
It might work 
It was only Meson and Mutagen that I wanted to update.
Thanks again
I found a solution to my problem 
Hope others may find it useful.
Load DevX first
In terminal I typed in the following:
pip freeze > requirements.txt
these gave me a list of packages that could be installed and then I typed in
pip install --upgrade --force-reinstall (package name)
to check that it had done this successful, typed in
pip list --outdated
