samasaur	Hi! I'm trying to package a NextJS NPM project with Nix, and I currently am able to build it on aarch64-darwin and x86_64-darwin, but not on Linux, and I really have no idea where to go from here	01:00:29
samasaur	The project is https://github.com/Remote-Text/remote-text-client/tree/nix-flake	01:01:04
samasaur	and the issue I get when building on x86_64-linux is npm ERR! code 1 npm ERR! path /build/379k76sxq5hfcb5azx75c2k0y66q9p1i-source/node_modules/cypress npm ERR! command failed npm ERR! command sh -c node index.js --exec install npm ERR!

samasaur	I tried adding `pkgs.cypress` to `buildInputs` and/or `nativeBuildInputs`, but neither seemed to fix the problem	01:02:40
@julia:the-apothecary.club	I believe that darwin's nix config defaults to the sandbox being disabled, so that's probably why it builds there. (one could verify this assumption with `--option sandbox true` on macOS or `--option sandbox false` on Linux.	01:09:40
@julia:the-apothecary.club	From googling, it looks like there's a `CYPRESS_RUN_BINARY` and `CYPRESS_INSTALL_BINARY` variable which allows you to set it to an existing path.	01:13:10
samasaur	In reply to @julia:the-apothecary.club I believe that darwin's nix config defaults to the sandbox being disabled, so that's probably why it builds there. (one could verify this assumption with `--option sandbox true` on macOS or `--option sandbox false` on Linux. `nix build . --sandbox` still works on Darwin, so I think that's not it	01:13:44
@julia:the-apothecary.club	* From googling, it looks like there's a `CYPRESS_RUN_BINARY` and `CYPRESS_INSTALL_BINARY` variable which allows you to set it to an existing path. (https://docs.cypress.io/guides/references/advanced-installation)	01:13:47
@julia:the-apothecary.club	Yes, but it's disabled by default.	01:13:52
samasaur	right but doesn't `--sandbox` enable it? so if it still builds with the sandbox, then that's not the issue?	01:14:57
@julia:the-apothecary.club	ah.	01:16:21
@julia:the-apothecary.club	In reply to @julia:the-apothecary.club From googling, it looks like there's a `CYPRESS_RUN_BINARY` and `CYPRESS_INSTALL_BINARY` variable which allows you to set it to an existing path. (https://docs.cypress.io/guides/references/advanced-installation) Yeah, you're right. I think this should still work though, cause the issue on Linux is trying to access the internet (which isn't possible in a sandbox).	01:17:16
samasaur	so maybe set `CYPRESS_INSTALL_BINARY=0` (to skip binary installs) and then set `CYPRESS_RUN_BINARY=${pkgs.cypress}/bin/Cypress`?	01:20:49
samasaur	will give it a shot	01:20:58
@julia:the-apothecary.club	Here's someone else's package using cypress: https://github.com/NixOS/nixpkgs/blob/d405cc8e0e47f8c45f72729000395f3eb3f73a70/pkgs/servers/monitoring/uptime-kuma/default.nix#L24	01:22:19
@julia:the-apothecary.club	(there's a few of those)	01:22:45
samasaur	thanks!	01:23:18
samasaur	In reply to @samasaur:matrix.org so maybe set `CYPRESS_INSTALL_BINARY=0` (to skip binary installs) and then set `CYPRESS_RUN_BINARY=${pkgs.cypress}/bin/Cypress`? also this appears to have worked!	01:23:24
samasaur	based on that package you linked I would think that `CYPRESS_RUN_BINARY` is unnecessary but I will leave it in there	01:23:54
@julia:the-apothecary.club	coolios. I guess mac must not download cypress? or do something different. which is kinda weird.	01:24:09
samasaur	honestly i think you were right and it's a sandboxing thing. i cannot prove it but i vaguely recall seeing a similar error initially on mac and doing weird NPM stuff outside of nix until it worked. so maybe that's still having an impact	01:25:29
@julia:the-apothecary.club	In reply to @samasaur:matrix.org `nix build . --sandbox` still works on Darwin, so I think that's not it actually, is this with a clean nix store / new build because `npmDepsHash` implies to me the npm deps get put to the store separately; it's not gonna try redownload if it's specified already. (not 100% on certain that's how it works, but I'd be surprised if it wasn't)	01:26:24

samasaur	oh true	01:26:49
samasaur	also despite it building on Linux, when i put it in a Docker image and tried to run the docker image, I still got `exec format error`	01:27:17
samasaur	so something else is wrong	01:27:30
@julia:the-apothecary.club	not particularly certain with docker things, what does `file` report?	01:31:11
samasaur	well `nix build . && ./result/bin/remote-text-web-client` runs fine	01:32:16
@julia:the-apothecary.club	is this purely on linux?	01:32:33
