`devenv gc` broken on MacOS ?

[gotcha]

When running devenv gc, I get the following error and output:

Counting old devenvs ...

error: flake 'path:/Users/gotcha/tmp/bad-devenv-gc' does not provide attribute 'packages.x86_64-darwin.default' or 'defaultPackage.x86_64-darwin'
/Users/gotcha/.nix-profile/bin/devenv: line 160: / 1024 / 1024 : syntax error: operand expected (error token is "/ 1024 / 1024 ")```

What are the steps to reproduce this?

[gotcha]

I installed devenv via

nix profile install nixpkgs#cachix
cachix use devenv
nix profile install github:cachix/devenv/v0.3

Steps to reproduce:

• $ devenv init
• activation via direnv
• $ devenv gc

@sandydoo could you test this?

[domenkozar]

Do you have M1 macos?

[domenkozar]

Can you paste /etc/nix/nix.conf?

Nope

I updated to 0.4 and get the very similar error:

✦2 ❯ devenv gc
Counting old devenvs ...

error: flake 'path:/Users/gotcha/tmp/test-devenv-0.4' does not provide attribute 'packages.x86_64-darwin.default' or 'defaultPackage.x86_64-darwin'

Works on my m1. It's an x86 issue or something with your used devenv.nix

[domenkozar]

Could you try using the latest main branch?

https://github.com/cachix/devenv/commit/93b562bd8706d1d5bb330c25be7ca780ddadbb8c might have fixed it.

@domenkozar Happy to test it. But I have no idea how to use the main branch ?

[domenkozar]

nix profile install github:cachix/devenv/main

[gotcha]

Not solved. This is what I did:

$ nix profile install github:cachix/devenv/main
$ mkdir bla
$ cd bla
$ devenv init
$ devenv gc

[domenkozar]

Had a call with @gotcha and it seems to be resolved, if it comes back let me know.
