Error with treesitter plugin

[gador]

Hi, I'm getting the following error:

Line   65:
Parser dir ' /nix/store/vhlasav5vp7c83ck32gq6csf205i06gg-vim-pack-dir/pack/myNeovimPackages/start/nvim-treesitter/parser ' should be read/write (see README on how to configure an alternative install location) /nix/store/vhlasav5vp7c83ck32gq6csf205i06gg-vim-pack-dir/pack/myNeovimPackages/start/nvim-treesitter/parser '

My config is the following:

programs.nixvim = {
        enable = true;
        colorschemes.base16 = {
          enable = true;
          colorscheme = "gruvbox-dark-medium";
        };

        };

        plugins.startify = {

          useUnicode = true;
        };
        plugins.treesitter.ensureInstalled = [
          "bash"

          "regex"
          "rust"
          "yaml"
        ];
        options = {
          number = true; # Show line numbers
          shiftwidth = 2; # Tab width should be 2
          mouse = "a";
          tabstop = 2;
          expandtab = true;
          smarttab = true;
          autoindent = true;
          cindent = true;
          linebreak = true;
          hidden = true;
        };
        extraPlugins = with pkgs.vimPlugins; [
          vim-autoformat
        ];
        maps = {
          normal."<F3>" = ":Autoformat<CR>";
        };
      };

Could you try manually setting plugins.treesitter.nixGrammars to both true and false? One of them might work.

Don't get me wrong, this is 100% a bug and I'm trying to figure it out, but I think I've had success with that workaround and manually doing :TSUninstall all followed by :TSInstall all

Hi @pta2002 thanks for the promt answer! Unfortunately neither option helped. It always results in the same error message about treesitter not being able to read/write. Only disabling treesitter completely got rid of the error message..

[pta2002]

This seems to be triggered by a change in treesitter. Upstream issue is here: https://github.com/NixOS/nixpkgs/issues/189838. For now, I'll see if I can implement the suggested workaround, but this seems like an upstream problem unfortunately

[gador]

ah, yes, I see. Thanks for investigating further!

[pta2002]

Temporarily fixed by implementing the suggested workaround if nixGrammars = true. This bypasses nvim-treesitter's parser management and installs all of the parsers directly from nix. Should fix a few issues regarding mismatched libc versions, too.
