配置通过NixOS的主管理器安装的vim

Question

我刚刚开始使用NixOS，我正试图通过home-manager来声明性地控制已安装的包，并将它们的配置部署到我的主目录中。

我告诉home-manager安装vim_configurable

# ~/.config/nixpkgs/home.nix
{ config, pkgs, ... }:
{
  home.packages = [
    pkgs.vim_configurable
    #...
  ]
  #...

它工作得很好，但是当我尝试使用program.vim来配置它时遇到了错误：

  #...
  programs.vim = {
    enable = true;
    settings = {
      expandtab = true;
      tabstop = 2;
    };
  };

运行home-manager switch会给我一个错误，原因是gvimdiff版本相互冲突

; home-manager switch
these 3 derivations will be built:

我猜这是因为programs.vim.enable = true指示home-manager添加系统vim，或者什么的，这是矛盾的吗？

删除enable = true可以消除错误，但是似乎没有任何配置设置，这使得指定programs.vim块变得毫无意义。

我做错什么了吗？这是应该工作的，还是这种配置期望我通过更新/etc/nixos/configuration.nix来安装软件包？

问题是，您需要选择一种方法:要么自己安装vim/vim_configurable，要么让主管理器为您安装。
