Problem starting the GHC Nix Shell

[tristangodfrey]

Apologies if this is a common issue covered somewhere but I was unable to find any relevant info in the docs/issues;

I get the following error when running nix-shell -A shells.ghc in the boilerplate project;

error: cannot coerce null to a string

       at /nix/store/76an527flbmhshw2mv8f9dh7gi38cz3b-source/pkgs/stdenv/generic/make-derivation.nix:192:34:

          191|         // (lib.optionalAttrs (!(attrs ? name) && attrs ? pname && attrs ? version)) {
          192|           name = "${attrs.pname}-${attrs.version}";
             |                                  ^
          193|         } // (lib.optionalAttrs (stdenv.hostPlatform != stdenv.buildPlatform && !dontAddHostSuffix && (attrs ? name || (attrs ? pname && attrs ? version)))) {

I'm assuming this is because a parameter is missing in a call to mkDerivation, does the shell depend on some external config that I should be injecting/defining in the host environment?

Thanks in advance (P.S., awesome project!)

While I don't know why it would matter in this case, note that we haven't tried testing with Nix >= 2.4 yet.

I get the same error, when installing reflex-platform using ./reflex-platform/try-reflex following this document: https://github.com/reflex-frp/reflex-platform/blob/develop/docs/project-development.rst

I am on macOS Monterey 12.1 using Nix v2.6.0

I managed to work around it by using Nix 2.3.16 using curl -L https://releases.nixos.org/nix/nix-2.3.16/install | arch -x86_64 /bin/bash

EDIT: This seems to cause a linker error ld: file not found: /usr/lib/system/libcache.dylib for architecture x86_64 when using nix-build though :(

Same over here, any progress on this?
