attribute 'stdenv' missing when installing obelisk on macos

[manyoo]

Hi, I'm new to obelisk and especially Nix. I tried to install obelisk following the instructions. I'm on a M1 MacBook Air with macOS Big Sur 11.6. Installed nix 2.3.15 and then try installing obelisk with:

nix-env -f https://github.com/obsidiansystems/obelisk/archive/master.tar.gz -iA command
but I get the following error:

~ nix-env -f https://github.com/obsidiansystems/obelisk/archive/master.tar.gz -iA command

Is this a bug in obelisk or Nix? Any idea on work around it and install obelisk? Thanks!

I should close this issue, because it's due to obelisk doesn't support ARM yet. The workaround is to re-install Nix x86 version, instead of the default ARM version. I downloaded the nix install script and changed the "system" variable to x86_64-darwin statically, then run the script to install. I've also added "system = x86_64-darwin" to /etc/nix/nix.conf so nix can always use x86 packages.

With the new nix installed, you can install obelisk again. obelisk works for simple demo projects. But due to obelisk and reflex-platform depends on older version of nixpkgs (20.09), which doesn't support macOS's new linker since BigSur, nixpkgs#91748, it won't work when more dependencies added. So, generally, obelisk doesn't work on Mac (intel and m1) for now. The best solution to this problem is updating obelisk and reflex-platform to nixpkgs 21.05 at least. @Ericson2314 mentioned they're working on that. @o1lo01ol1o tried to backport the nixpkgs fix back to 20.09, but it will re-compile almost all packages due to no binary cache available. I tried twice and both failed. You can learn more about it here: obelisk#869.

Currently, I run obelisk on a linux machine, and use VSCode on my Mac with remote ssh plugin to code. It has all ghcide features available as well.
