On an Ubuntu or Debian related distro you would sudo apt install pip. Then you could run the python3 -m pip install --upgrade pip to make sure you have the latest pip. Finally use pip to install poetry. But maybe you should use python3 -m pip install poetry.
It depends on which version of python is in use. It can get kind of convoluted. The default on the computer should not be messed with. Typically, you want to use virtual environments for each project. I think that’s what they are trying to do with poetry, but I have not used poetry.
I think the instructions for installing pip were incorrect.
Pip , and therefore Python, belong to the class of software items which subvert the package system by installing things
outside of it.
There is a growing list of these rebels , including languages such as R , Julia, and Rust…
It would seem some languages have a problem using the package system. The older languages, C, C++, Fortran do not do it… it is the newer, fast developing languages that seem to want to create their own package system, when there is a perfectly reasonable and well tested one already available.
Re-inventing the wheel is not usually a useful activity.
I just want to add here that following the steps in the article caused me all kinds of issues. I was not aware of them until I rebooted.
Eventually had to get recovery mode, repair broken packages, which all output errors pointed to python 3.11. Luckily, I was able to update, remove the ppa & packages without reinstalling python completely and got my working system back.
That’s what I meant by saying the default Python installation should really be left alone. I don’t remember for sure but I think they said the article was written with Python 3.11 in mind. The default was probably more like Python 3.9.
It is tricky to work with Python where there are multiple versions required and virtual environments used. I can’t say I’m an expert. I’m just aware of the variables.
