That's one of the big reasons why I've been Nixifying my React Native projects, and gradually it seems to be working out. A number of projects seem to be starting to do something like that as well, like status-im, and occasionally I find their configs helpful. By itself, Nix doesn't help with the M1 React Native problems, but with fastlane, Ruby, cocoapods, things really nicely just worked, and once I've figured everything out once, I'll be able feel a breath a relief the next time I come around (except I suppose Xcode, which isn't properly Nix-able).

Yes and no.

I mean, I think this is absolutely the killer feature of Nix (even above the more accessible asdf, since Nix will also provide native libraries); it's really nice to get a development environment which will Just Work. (OP's frustration isn't unusual).

On the other hand, Nix doesn't make problems disappear; and can require having a deep understanding of what the problem encountered is. OP ran into problems trying to get a project which had worked on (presumably) x86_64 macOS, but didn't work on M1.

I don't understand the love for asdf. It doesn't support node versions like let's/gallium. It doesn't support Python venvs. Back to nvm and pyenv-virtualenv for me.
