MELPA now ignores upstream lispy-pkg.el files (ce48c84), so the nix-built lispy no longer propagates its swiper dependency and byte-compiling lispy-occur.el fails with require(swiper). This override adds it back:

nix:tangle ~/nix/overrides/lispy.nix

lispy = let
  old = epkgs.lispy;
in old.overrideAttrs {
  packageRequires = old.packageRequires ++ [
    epkgs.ace-window
    epkgs.avy
    epkgs.hydra
    epkgs.iedit
    epkgs.swiper
    epkgs.zoutline
  ];
};
