error: Component resolution failed for rust-default-1.54.0
Apple M1s are uncharted territory for me. i don’t posses one and don’t plan on changing that anytime soon. however, i searched around the webs and found that you can enable x86_64 mode on it using this command arch -x86_64 zsh. if you run that before installing nix and running the nix-shell it hopefully works as well as on x86_86 macOS. i’m curious if this does work so please let us know!
i know that @lucksus had access to such a machine so maybe he can share his experience as well.
Thanks @steveeJ
Your suggestion works, I can install x86 nix and run tests of elemental-chat in nix-shell (3 of 49 tests failed though).
But using this way, it’s pretty slow and I’m having network issues from time to time. Not sure if it’s my own case or a general issue.

I actually didn’t get my M1 macBook until today. I was waiting for the pro versions to come out and finally received mine now
The problem I was fighting almost all day today and finally got the solution from @kaichao (thanks!) was the error too many open files when entering any nix-shell.
This is what @kaichao suggested and made it work for me:
Tried only changing the file limits before. Stopping (=restarting, since nix-shell will start it again) the nix-daemon seems to be crucial since it is the process opening those files, not the shell in which you call nix-shell.
After solving that problem, I could even build Holochain for arm64 natively, that is without arch -x86_64 zsh as @steveeJ suggested. Instead I did export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 as nix-shell suggests, if you want to try building an unsupported package anyways.
I could install nix-shell and cachix following @lucksus advice:
You could set this variable permanently on your Shell configuration file. I’m using ZSH, then I added to config file ~/.zshrch this:
# Holochain.love
alias nshl="nix-shell https://holochain.love" # This is for running `nshl` command instead of `nix-shell https://holochain.love`
# Allow holochain.love that is unsupported for this system (aarch64-darwin)
export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1
