Thanks to @adamw, who dared to suggest we try it, we now have a small patch for #virtualenv in #Fedora to enable creation of #Python 3.6 virtual environments.

Hence, you can use #tox to test your code on Python 3.6 to 3.15, without the need for nasty hacks -- https://github.com/tox-dev/tox/issues/3656

Supporting testing on 3.6 is important to us, as many developers targeting #RHEL 8 still need to support it. (Python 3.6 is the new Python 2.6.)

Anyway, test it out:

#Python #Pip #VirtualEnvironment #Virtualenv #Programming #Linux

I've just done a full upgrade of my laser-cutter laptop from #DebianBookworm to #debian13trixie and it went pretty well - I'm flexing the current lack of #brainfog while it lasts! You always expect some wrinkles with big updates like this, but the only thing that looks like it broke and needed manual intervention to fix was a Python #virtualenv that I use for running #svg2gcode and some scripts I've built around it. There's not much in the venv, so it was easy to just re-create, and for future me, I've made a list of the installed packages so if I ever need to do it again, it'll be easier. Going to run with this for a while before I tackle my main laptop, and later, my wife's - you'd never believe the SLAs in the contract for THAT support gig! At least she's finished her dissertation now, so the pressure is somewhat lower.

I kind of irrationally #CodeGolf my #Makefile rules, but sometimes I sit down to straighten out something awkward that bugged me for years, and get kind of mad when I seem to have been the first to actually treat `make` like the tool it is instead of as a broken shell script runner.

This time it was #Python #VirtualEnv setup:

```
dep: .venv/bin/pip .venv/lib/*/site-packages/__pycache__

.venv/lib/%/site-packages/__pycache__: .venv/bin/pip requirements.txt
.venv/bin/pip install -Ur requirements.txt

%/bin/pip:
/usr/bin/virtualenv $*
```

(Yeah pretend those are tabs. Yeah that is make's worst wart.)

I even use `!#.venv/bin/python3` in my scripts and hey presto everything just works everywhere and I can focus on the actual code.

I'm curious what cases I'm ignoring or missing here. Non-install upgrades may deserve a target perhaps...

Holy fuck! I know I’m late to the game but uv is amazing! A single binary for managing python deps, envs and even python versions! Nice to see it’s been written in rust too! And it’s really fast! https://docs.astral.sh/uv/ #rustlang #python #virtualenv #pip

So, I'm tinkering a bit with #Django, and I wanted to run different Django versions on the /same/ virtual machine. Here `#virtualenv` helps only insomuch that it can seperate dev envs, but it all still shares the `~/.local/lib/python3.10/site-packages` folder.

(I can't imagine this problem hasn't been solved, but couldn't find anything online.)

I've resorted to overriding HOME: basically I wrote a `virtualenvenv` script that I source, and then I have the separation I want/need. 🔨

For some reason, since this morning, the #pip that I installed via #pipx does not work with my other #virtualenv setups anymore (it installs all packages in its own pipx venv instead of the currently active venv).

Has anyone else encountered this issue? It makes pip virtually (hoho) unusable!

#python #venv #virtualEnvironment

If I had the time and energy I would:

• Make a #ThonnyIDE plug-in to launch #JupyterLab from the Thonny GUI interface (using Thonny's #Python #virtualenv;
• Write some code to convert #geoDataFrames with a graphic attributes column into #py5 styled shapes;
• Make a search interface to my daily sketch-a-day sketches and fix the RSS.

My final boss in solving this #Django on #Alpine container thing is getting #Apache/#WSGI (mod_wsgi) working. My container runs Apache fine, I suppose, if I don't supply it any site config - but once I do (i.e. in /etc/apache2/conf.d), I'm getting Segmentation fault core dumped errors and reboots.

I'm assuming, as far as my config goes, I need to point python-home to where my #virtualenv is, in addition to python-path to where my Django site/app is (like I do on #Ubuntu since that does not enforce the use of venv yet). But that doesn't seem to be enough, so again, in addition to apache2, apache2-mod-wsgi, and apache2-utils (and perhaps musl-dev and gcc in runtime other than just during build), what am I missing?

@mckean
I presume you are speaking about the package and project manager uv?

Sounds interesting, thanks for the impetus to take a look at it.

Hey #Fedi, can you help me with a #Python environment pain-point?

TL;DR : I want global #virtualenv management

I've been using virtual environments for quite some time, but I might be missing some standard feature because switching env is a pain: I have to be in the right folder (where the venv dir was created) or manually configure a shell script.
Is there a tool that can provide me with the equivalent of ``envswitch envname`` regardless of the folder I'm in?

quicktipp #97: Sharing Python environments on Windows using portable Python Bundles.

https://dev.to/treehouse/portable-python-bundles-on-windows-41ac

#python #pip #ven #virtualenv #windows

After programming a good 2 months in #python finally found the tool #poetry which is quite similar to how #nodejs bundles libraries into a directory either locally or globally in the cache directory.

I have tried the other tools from #pyenv to #venv and/or #virtualenv. Where I thought they were used to deal with library dependency management only to realize that they are more like #nvm.

I did use #conda for some time, though preferred a python only solution. I do realize that poetry won't resolve all issues and might need to look into to containerization later on, though for the time period it looks like a good solution.

I keep referring to this blog post of mine a lot. I'm glad I took some time to note all my process so I can reuse it int he future (and hopefully it's useful for other people too)

Can you try installing it with `pipx` instead?

pipx will create a Python virtualenv just for that program, and install all of its dependencies into that virtual environment. It can then run independently of any system-level versions of those same packages that are installed *for the distro-shipped Python tools*.

The version pipx installs can be upgraded (or left alone) completely independently of OS updates.

#pip #pipx #virtualenv

Just tried the #uv #Python management tool. At first I thought: Oh no, not another Python package manager. But this one seems different. It combines all the pip-tools, #pyenv, #poetry, #virtualenv, etc in one.
And it's damn fast. This likely will stay with me for a while.

https://docs.astral.sh/uv/

I'm trying to use mypy inside tox with tox-uv, but mypy's --install-types flag hardcodes the usage of pip. When you're using tox-uv, pip is no longer installed in the environment because uv does the heavy lifting with `uv pip install` as a faster alternative to `pip install`

Here's my attempt at making mypy more configurable so it can install types using uv:

Why is Python special in this regard? Many applications, whether written in Python, Perl, Ruby, or C etc, embed a particular version of a library because they either can't rely on it being available system-wide, or because they can't rely on the system-provided one being completely #compatible with their needs.

I find virtual environments an elegant solution to the problem, better than many other languages' solutions.
