I believe the issue is related to NixOS/nixpkgs#91748 however I have no idea to fix it

[kenranunderscore]

I'm having this problem too. Looked through the other issue(s) and it seems like it's the same problem or related, but I don't fully understand it. So I, too, have no idea how to go about this.
I'll do the "dumb" step and try reinstalling nix and the XCode command line tools... though I don't think that should change anything.

[MurakamiKennzo]

does this have any solution? I have the same problem is there a way for build front-end application?.

[alt-romes]

I believe the issue is the outdated version of nixpkgs; I changed the rev and hash to master to see what would happen, but there's a cascade of errors doing this small bump.

@Ericson2314 I don't know nix, how feasible is it for me to bump this on my own? How bad is it for anyone experienced? Fixing this would be really cool.

Yesterday I lost quite some time on it with little to show

[Ericson2314]

It is quite hard, I am afraid.

[Ericson2314]

#768 is an attempt I started after we did a view round. I am a strong believe one should go from one stable Nixpkgs to the next, and not skip versions.

[ali-abrar]

#768 was merged some time ago, which should have fixed this issue.
