在vim_configurable.customize中使用python3覆盖python3

Question

我在使用this模板来配置我的自定义vim和Nix。我vim-config/default.nix如下：

{ pkgs }: 

let 
    my_plugins = import ./plugins.nix { inherit (pkgs) vimUtils fetchFromGitHub; }; 
in with (pkgs // { python = pkgs.python3; }); vim_configurable.customize { 
    name = "vim"; 
    vimrcConfig = { 
    customRC = '' 
     syntax on 
     filetype on 
     " ... 
    ''; 

    vam.knownPlugins = vimPlugins // my_plugins; 
    vam.pluginDictionaries = [ 
     { names = [ 
     "ctrlp" 
     # ... 
     ]; } 
    ]; 
    }; 
} 

虽然有(pkgs // { python = pkgs.python3; })覆盖在第5行，仍没有使用python3（当我运行vim --version它显示+python -python3）。我错过了什么？

事实证明，with (pkgs // { python = pkgs.python3; });只修改python在with语句后面的范围内。 vim_configurable中使用的python不受影响。我落得这样做是让使用vimUtils.makeCustomizable的vim_configurable一个python3版本：

vim-config/default.nix：

{ pkgs }: 

let 
  my_plugins = import ./plugins.nix { inherit (pkgs) vimUtils fetchFromGitHub; }; 
  configurable_nix_path = <nixpkgs/pkgs/applications/editors/vim/configurable.nix>; 
  my_vim_configurable = with pkgs; vimUtils.makeCustomizable (callPackage configurable_nix_path { 
    inherit (darwin.apple_sdk.frameworks) CoreServices Cocoa Foundation CoreData; 
    inherit (darwin) libobjc cf-private; 

    features = "huge"; # one of  tiny, small, normal, big or huge 
    lua = pkgs.lua5_1; 
    gui = config.vim.gui or "auto"; 
    python = python3; 

    # optional features by flags 
    flags = [ "python" "X11" ]; 
  }); 

in with pkgs; my_vim_configurable.customize { 
  name = "vim"; 
  vimrcConfig = { 
    customRC = '' 
      syntax on 
      “... 
    ''; 

    vam.knownPlugins = vimPlugins // my_plugins; 
    vam.pluginDictionaries = [ 
      { names = [ 
        "ctrlp" 
        # ... 
      ]; } 
    ]; 
  }; 
}
