Aspell dicts missing

Help
1

First time to use aspell, I found some dicts missing.

  • Installation
    (aspellWithDicts (
      dicts: with dicts; [
        en
        en-computers
        en-science
      ]
    ))
  • Check available dicts, it doesn’t shows either en-computer or en-science? Are they missing?
