Mario (Oct 14 2022 at 09:44): Mario (Oct 14 2022 at 09:44):Hey all – bit stuck trying to refresh my roc env after some time.
Reinstalled nix to get latest version, and now getting this odd error:
# mario ~/dev/projects/roc ± main o 10:40:31
$ nix develop --show-trace
error: getting status of '/nix/store/6pakgwxwz07gifgrzgckj6730qmk9k1g-source': No such file or directory
… while realising the context of path '/nix/store/6pakgwxwz07gifgrzgckj6730qmk9k1g-source/flake.nix'

20| flake = import (sourceInfo + (if subdir != "" then "/" else "") + subdir + "/flake.nix");
| ^

… while evaluating anonymous lambda

...etc
Have tried nix store delete --all to clear everything out, destroying the target folder... can't seem to find where/why this nix pkg ref is occurring nor how to progress this any further.
Mario (Oct 14 2022 at 09:44):$ nix --version
nix (Nix) 2.11.1
I'm not sure I can help you much. I'm running nix 2.11.0 on macOS and the latest main and it seems to be working fine. I upgraded to the latest stable nix version which was the same version. I wonder if there is an issue being 2.11.1?
Anton (Oct 14 2022 at 10:19):Hi Mario, can you confirm that this is a recent main without any changes (git status)?
Mario (Oct 14 2022 at 10:45):$ git reset --hard origin/main
HEAD is now at 89a4522fa Merge pull request #4178 from roc-lang/macos-11-nightly
# mario ~/dev/projects/roc ± main o 11:45:18
$ nix develop
error: getting status of '/nix/store/6pakgwxwz07gifgrzgckj6730qmk9k1g-source': No such file or directory
(use '--show-trace' to show detailed location information)
I think nix store delete --all is being a bit too careful, I would give rm -rf /nix/store/* a try.
Mario (Oct 14 2022 at 12:15):Doing that means nix binary disappears as well (same cycle I went through before). Re-ran the nix install again, now failing here

Jeeze, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.
:(
We'd love to help if you need it.
You can open an issue at https://github.com/nixos/nix/issues
Or feel free to contact the team:
- Matrix: #nix:nixos.org
- IRC: in #nixos on irc.libera.chat
- twitter: @nixos_org
- forum: https://discourse.nixos.org
It's all feeling really wrong :/
Mario (Oct 14 2022 at 12:16):1600 issues on nix repo so doubt I'll get much help there
Mario (Oct 14 2022 at 12:17):# mario ~/dev/projects/roc ± main o 13:14:26
$ nix
zsh: command not found: nix
Whelp, that's the end of roc play time for today :sweat_smile:
Anton (Oct 14 2022 at 12:21):Yeah sorry, I'd recommend looking up how you can remove all files and folders created by nix for your OS and doing a clean nix install.
If you just want to write roc without contributing to the source code you can try the nightly releases.
Mario (Oct 14 2022 at 13:27):Yeah okay, sadly uninstalling is confusingly involved, so I'll have to return to that later. I wanted to make a inconsequential contribution to docs styling and figured I could get the cargo stuff running quickly that way as I was having issues using cargo build directly.
Anton (Oct 14 2022 at 13:46):I'd be happy to try and fix the regular cargo build as well if you're willing to share the error message. I've setup building on many devices, VMs and CI machines so it's likely to be a familiar error.
Mario (Oct 14 2022 at 14:45):Sure!

Ah – if 'zig failed' means zig wasn't installed (looks like its missing now since nix broke), installing it and re-running gives:

Which is weird cause

what does zig version output?

$ zig version

Ah, have installed 0.9.1 and it seems to be carrying on :thumbs_up:
Mario (Oct 14 2022 at 14:51):Didn't realise I installed master as it was listed at top of zig install page
Richard Feldman (Oct 14 2022 at 14:52):nice, yeah we can't upgrade to 10 until we upgrade llvm versions, which is nontrivial
Richard Feldman (Oct 14 2022 at 14:52):so we're still on 0.9.1
Mario (Oct 14 2022 at 14:52):Cool. So I guess I can perhaps crack on without nix for now? Are there docs somewhere for how to build the docs?
Mario (Oct 14 2022 at 14:53):My rust is... rusty :D cargo build fine but seems cargo run is a no go on crates or something like that.
Mario (Oct 14 2022 at 14:57):Will follow https://github.com/roc-lang/roc/blob/main/BUILDING_FROM_SOURCE.md a little further later and see if I manage to get further
Anton (Oct 14 2022 at 15:18):Are there docs somewhere for how to build the docs?
Not yet I believe, I think you can extract what you need from www/build.sh.
Richard Feldman (Oct 14 2022 at 15:18):this is how we build the docs on CI: https://github.com/roc-lang/roc/blob/89a4522faa20ee0b3ed0cdeaab07379873b95c3f/www/build.sh#L28
Anton (Oct 14 2022 at 15:19):My rust is... rusty :D cargo build fine but seems cargo run is a no go on crates or something like that.
Most crates are libraries so you can not run them.
Mario (Oct 14 2022 at 17:26):Awesome, got it building :) thanks for the help!
