> re: ruby version I hoped you would tell me how to pin a specific version in nix, and you didn't. So far, I've asked this question at least three times. This question is either avoided or ignored. Ah yes. There's one "solution" with overlays which is neither maintainable nor scalable. > ruby version In ubuntu Is nix ubuntu? > What is possible is to pin the version you need by specifying the commit. Commit hashes are not versions > I would need to use rvm anyway. It's the same with nix We keep hearing the claim that nix is about builds. Builds often need their dependencies pinned to specific versions. If I still need to use rvm with nix, what's the point? This is especially funny in the context: we're in the comment section to a post claiming that we should ditch our "version managers" while providing an alternative that, so far, looks to be significantly worse at what it claims to do.
