文档 里使用 home-manager 时，当使用 sudo nixos-rebuild switch 会出现这个问题：
Issue in the documentation: Error occurs when using sudo nixos-rebuild switch command with home-manager:

       error: 'exa' has been removed because it is unmaintained upstream. Consider using 'eza', a maintained fork

Solution: Replace the following block:

home.packages = with pkgs; [
    # ......
    yq-go # yaml processer https://github.com/mikefarah/yq
    exa # edit here! 修改这里！
    fzf # A command-line fuzzy finder
];

with:

home.packages = with pkgs; [
    # ......
    yq-go # yaml processer https://github.com/mikefarah/yq
    eza # Fine!
    fzf # A command-line fuzzy finder
];
