you'd define an environment with the required deps versions, for example github.com/ropensci/rix...

this is the default.nix to develop rix. If I needed a specific version of some dependency, I'd add it there.

I'm not sure I understand what you're trying to do, could you describe what you're trying to achieve?

you can have a specific environment with specific packages per node, see github.com/b-rodrigues/...

that being said mojo is not included in Nix for now

here's an example where both R and Python are used github.com/b-rodrigues/...

thanks! of course one could ask why one would need to use machine learning for predictions since the solved model is right there, but the point was to show how easy rixpress makes using different languages for one single project 😁

thanks for the feedback, really cool to see it being useful to others!

cool! if you have questions don't hesitate !

btw, how long have you been using Nix? you use it only inside Docker? why not directly on your machine?

enjoy bit-for-bit reproducible environments!

let's goooooooo

this is very strange; is direnv working correctly? restart wsl, cd into the project, and type which R: is the path you see from the nix/store? this looks like direnv is not doing what it's supposed to. Did you put the two lines inside of the .envrc file?

did you run direnv allow in the project directory? did you restart everything once? what happens if instead you type positron in the nix-shell ?

you said you reinstalled wsl: did you also install direnv in wsl, the direnv extension for positron and setup the hook in .bashrc?

you also need to close and reopen the WSL terminal after installing nix

no, never seen this issue. where are you trying to run this? everything needs to run inside the wsl terminal (installing nix, cachix, running the rix scripts, etc)

if you’re using it inside docker, you could do it like so github.com/ropensci/rix...

mmh, you shouldn't have to open Positron from WSL. Opening from the windows start menu, and from Positron, opening a project should work. I wonder if Positron's linux terminal might be using some other distro than your main WSL distro. I've seen this happening with students.
