nixos-install error with modules.nix

Hi, I am new to Nixos and wanted to have quickstart with your awesome config, but I am stuck with an error while using "nixos-install ....".

Not sure if I made mistake or if it is a general error. So I decided to post here after a long search on google.

Used command: nixos-install --root /mnt --flake .#ai --no-root-password --option substituters "https://mirror.sjtu.edu.cn/nix-channels/store"

Error:

building the flake in git+file:///root/nix-config...
warning: Git tree '/root/nix-config' is dirty
error:
       … while calling the 'seq' builtin

             |                  ^
          321|         _module = checked (config._module);

Thanks for your help in advance.

After adding --show-trace option, the error log should be:

The error indicates nix could not found an argument named impermanence in its args and specialArgs.
