treesitter Neovim 插件在 nixos 上不起作用

Question

我已将家庭管理器作为模块安装在薄片中。
Flake 和模块位于/etc/nixos/.
我的家庭管理器文件链接到我在其中配置 neovim 的另一个文件，该文件位于/etc/nixos/config/nvim/nvim.nix.
该文件的内容是

# neovim configuration file

pkgs:

{
  enable = true;
  vimAlias = true;

  # A simple configuration for neovim (sourced files)
  extraLuaConfig = ''
    -- Indentation
    vim.opt.smartindent = true
    vim.opt.autoindent = true

    -- UI settings
    vim.opt.number = true
    vim.opt.cursorline = true
  '';


  plugins = with pkgs.vimPlugins; [
    vim-nix
    yuck-vim
    markdown-preview-nvim
    {
      plugin = telescope-nvim;
      config = ''
        " Find files using Telescope command-line sugar.

              '';

    }
    {
      type = "lua";
      plugin = catppuccin-nvim;
      config = ''
        require("catppuccin").setup({
          flavour = "mocha", -- latte, frappe, macchiato, mocha
          background = { -- :h background

          styles = {
            comments = { "italic" },
            conditionals = { "italic" },
            loops = {},
            functions = {},
            keywords = {},
            strings = {},
            variables = {},
            numbers = {},

            gitsigns = true,
            nvimtree = true,
            telescope = true,
            notify = false,
            mini = false,
            -- For more plugins integrations please scroll down (https://github.com/catppuccin/nvim#integrations)
        },
    })

    -- setup must be called before loading
    vim.cmd.colorscheme "catppuccin"

      '';
    }
    nvim-web-devicons
    neo-tree-nvim
    {
      type = "lua";
      plugin = nvim-treesitter;
      config = ''
        require'nvim-treesitter.configs'.setup {
          ensure_installed = "maintained",
          highlight = {
            enable = true,
          }
        }
      '';
    }
    nvim-lspconfig
    rust-tools-nvim
  ];

  extraPackages = with pkgs; [
    tree-sitter
    rust-analyzer
    ripgrep
    nil
    zig
    ripgrep

        lazygit
  ];
}

当我打开文件时，例如，*.lua我收到错误消息：

Error detected while processing /home/simon/.config/nvim/init.lua:

re/w3x3582xldrjymxbxz98lzlfmhazibmy-vim-pack-dir/pack/myNeovimPackages/start/nvim-treesitter/parser: read-only file system

我怎样才能解决这个问题？任何帮助是极大的赞赏。

您可以使用 nvim-treesitter 安装 Tree Sitter 语法nvim-treesitter.withPlugins。像这样的东西应该开箱即用

nvim-treesitter.withPlugins (ps: with ps; [ nix python ])

如果你想安装所有语法：

nvim-treesitter.withAllGrammars

这记录在NixOS 手册的 vim 部分

如果您不想使用 nix 安装 nvim-treesitter 语法，您可以将 设置parser_install_dir为可写的，请注意，这可能无法开箱即用。

require("nvim-treesitter.configs").setup({
  parser_install_dir = "/some/path/to/store/parsers",
})

:h nvim-treesitter-quickstart这些信息可以通过在 neovim 中运行来找到。
