How to install up-to-date python for a user only?
2 years ago by boredsquirrel (he) to c/linux
You know, immutable enterprise systems.
I installed HeliumOS (Almalinux bootc) on a corebooted Chromebook. Works really well, but audio needs to be configured.
The script needs a recent python which is not available there.
Go and rust can be installed for a user only. Is there something similar for python?
Plus one for pyenv
You might consider trying Miniconda, a version of Anaconda. It installs a local python environment of your choosing at a user level. https://docs.anaconda.com/miniconda/
I Gave it a try on macOS a few days ago because brew and python is a dependencie hell and way to much workarounds to make some scripts to work properly when specific versions of packages are needed...
Miniconda actually made it work fine, without to much hassle. I'm kinda impressed.
I prefer Micromamba since it's faster at solving environments.
If you can install nix (you can install it per user) then you can have whatever you want in a temporary shell with nix-shell -p python
nix profile install nixpkgs#python if you want it actually installed
Home manager is also entirely user level I believe and lets you use a declarative config too
I tried to get install instructions for home-manager and they only had them if you are already on nix?
I didnt get it
I'd try installing just regular nix (package manager, not operating system) rather than home manager, that's what I do on by Debian pi
There's an install script on their website that does it all for you
Nice! Yes I will do that. What is the difference between the 2?
Careful, there's three different terms in the mix here:
NixOS: an entire operating system, you don't need this.
nix: the nix package manager. This is what you'll need to install. look for single user install in the instructions.
home-manager: a module for nix. It's aim is to allow declarative configuration of a users' home configuration (and allow easier per-user install of packages on a global nix install).
If you want to go down the nix route, which I would recommend if you enjoy tinkering and having fine control over your system, you should start with installing nix. With that, you can already setup a shell that has the newest version of python available.
Going beyond that, I can link you some more resources, if you want c:
So "nix install" means placing a nix binary somewhere in my user $PATH?
Does home manager work standalone without having nix first? I've never installed it on non-nixos
Nix shell is absolutely for running packages without installing them it literally tells you to do that in the terminal hint
Nix run iirc only works with flakes
No, it builds on top of nix. But it seems like the only real option for declarative package management.
Nix shell and nix-shell are different commands
https://discourse.nixos.org/...
Nix run iirc only works with flakes
So does nix shell
nix shell -p works without flakes enabled
Interesting, didn't know the history of the command. But that post confirms my understanding, that nix shell/develop are the new replacements for nix-shell, with nix shell for temporary package installs and nix develop for debugging and developing
Can you use pyenv for the script?
You should be able to have multiple versions with an environment manager, maybe customize your shell profile to alias python to the one you want and the other users can alias to the one they want. I’m sure there’s a better way, but I strongly dislike python every time I try to learn it because Perl was the first language I learned, ruining me for strongly opinionated languages.

One solution could be to install uv for a single user, and use that to install and run a Python interpreter.
Compile it, install it to your ~/bin.
~/.local/bin ;)
But yes, great idea.
I found a script online that installed the tar archive. For some reason that version of python still wasnt used, and invoking it with python3.12.6 or something didnt do anything
~/bin is the real directory for UNIX.
It is?
https://cvsweb.openbsd.org/src/etc/skel/dot.profile?rev=1.8&content-type=text%2Fx-cvsweb-markup
Have you considered using pipx + poetry?
~/.local/bin you mean?
;)
Yes I tried that, and got like 6 different solutions to do this so I will see :)
Not yet fixed, no motivation
Audio configuration sounds like a shell task. Why does it need Python? Is this script in any way an official part of the OS?
No not a part of the OS and als no idea why they used python, that script is full of crazy functions so may be needed.
I translated the python 3.12 to 3.9 using ChatGPT lol, as even after installing up-to-date python and placing it in my home $PATH the script threw errors.
I think it worked, but there is an issue with my atomic system, so I likely need to build an RPM for the changes or use a different command for akmods or package the kernel myself or whatever.
Ah, I see. Well I'm glad it worked!
I am on a Chromebook and that is a recommended script. There are really just a few functions in python 3.11 that are missing in 3.9
This script? https://github.com/...
I'm not familiar with bootc based systems but it looks like you could hack up the container spec here: https://codeberg.org/HeliumOS/bootc to build heliumOS with those changes. You would then use something like bootc switch ... to use it.
(Add a line in the docker file to install newer python and run the audio script. I'm not sure if the script requires changes for this.)
I could be way off base with this idea, I'm not sure how heliumOS expects users to install packages.
You may also be able to run the latest python docker image to run the script, but the way this script modifies system files shouldn't work on an immutable system.

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Doesn't pyenv solve?
