Nix allows you to do this with any language and required dependency: https://wiki.nixos.org/wiki/Nix-shell_shebang

Now you have to set up Nix first and deal with that nightmare of a learning curve. Just to auto-install some dependencies for a script.

Might as well rewrite all your scripts in Rust too while you're layering on unholy amounts of complexity.

It’s like Vim, you learn it once, and you keep using it forever once you’re used to it.

I’m so thankful to see a flake.nix file in every single cool project on code forges.

Yea that's a common theme of excuses for both Rust and Nix. Wrong though, because most anyone who can use a computer at all can learn the basics of Vim.

Seeing that flake.nix badge of complexity lets me know a project will be a nightmare to set up and will break every other week. It's usually right next to the Cargo.toml badge with 400 dependencies underneath.

		Nix with Flakes never randomly break, I still have projects from 3 or 4 years ago that I can still run `nix build` and getting it running. Yes, if you try to update the `flake.lock` this may introduce breakages, but this is expected if you're pining `nixos-unstable` instead of a stable branch.

Whoa! This is a revelation. I already loved Nix and used nix-shell extensively, but this is the missing piece: fully reproducible Python scripts without compromise.

		Or install direnv and put your dependencies into a shell.nix, setup the bash hook according the manual, create the .envrc with the content "use nix". Then type "direnv allow". Then you can do e.g. use other persons python scripts without modifying their shebang.
