fails with ln error

[gilligan]

For me buildYarnPackage fails while building the offline derivation:

these derivations will be built:
  /nix/store/glyvw2rgb93g8yd2s9r4lz60nq1wyyd5-offline.drv

Sadly I cannot share the files I am trying this with. The setup is basically:

with (import ./yarn2nix.nix { inherit pkgs; });

where yarn2nix is the default.nix file from this repository. Then I just call buildYarnPackage ..

    buildYarnPackage {
      name = "app";
      src = ./.;
      packageJson = ./package.json;
      yarnLock = ./yarn.lock;
      yarnNix = ./yarn.nix;
    }

@moretea any idea what might be going on here?

Can you paste the yarn.lock? I am looking for weirdly-named package names.

Basically this is the line which it's tripping over:

ln -s ${deps}/node_modules/* $out/node_modules/

It's probably a globbing expansion issue, a name with spaces or with dashes.
