求教个darwin下nix home-manager的问题

Programming
1

Hi,

我在macos下安装home-manager的时候发现swtich错误。是这两行的原因 dotty-nix/options.nix at 3323897abecdca6cf933173820068d2348a2b883 · ztlevi/dotty-nix · GitHub. 我如果把这两行去掉，是能够build的，但奇怪的是，我在nixos下是能正常switch的。

我试了home-manager master 和20.03的channel都不行，有没有大佬帮忙看下是什么问题。下面贴了错误信息。

我安装home-manager的流程在这边https://github.com/ztlevi/nix-dotfiles/blob/darwin/Makefile#L87-L92

你为啥问nix的问题在emacs论坛，这个提示已经很清楚了。 evaluating the attribute ‘values’ 不对value is a function while a set was expected 查看对应的nixpkgs channel lib要求。那nixos可能nixpkgs channel lib是不同版本的。

3

因为在nix论坛问了没什么回复。。。

我找到问题了，是options.my.users的定义不对。估计是nixpkgs-unstable的定义和stable版本的定义不一样。

解决了这个问题以后又报错，说

building the system configuration...
warning: Nix search path entry '/nix/var/nix/profiles/per-user/root/channels' does not exist, ignoring
error: The option `my.packages' is used but not defined.
(use '--show-trace' to show detailed location information)
make: *** [Makefile:84: switch] Error 1
make: Leaving directory '/Users/ztlevi/.dotfiles'

是这行的问题，但我明明在上面的optiolns里面定义了啊。https://github.com/ztlevi/nix-dotfiles/blob/darwin/options.nix#L69

求教是什么问题啊？

4

这个意思说你没set 已经说的很明白了。mkoption后要有default set 到你de listof package 你可以设置 default = [];就好 packages = mkOption { type = with types; listOf package; default = []; };

5

谢谢，估计是新版本默认得设置了 :joy:

楼主，请问下在Mac上安装Nix 可以替代homebrew吗，准备入坑nix。有没必要卸载brew？

7

homebrew 要留着 cask（除了cask，一无是处

8

多谢，刚装好nix，看来得看一遍手册才行。brew跟nix 功能重叠，准备卸了，留着cask安装gui应用。
