node2nix-derived build fails

[mrobbetts]

This is my first time using node2nix, sorry if I am missing something silly.

I am trying to package Shinobi CCTV, and have successfully invoked node2nix to generate the relevant nix files. I then include them in my new derivation in the normal way, and then try to get the package to build.

There was a ton of new dependencies to build, and a big chunk of them built fine. But one fails reliably:

# nix-build /nix/store/ad2rizzv3l02f55nn1g8l6wj51q4k1vi-onvif-9742ea1.drv
this derivation will be built:
  /nix/store/ad2rizzv3l02f55nn1g8l6wj51q4k1vi-onvif-9742ea1.drv

I have no idea why this might be failing to find ssh? Is this an obvious error on my part?

The relevant snippet of my node-packages.nix for this dep is:

"onvif-git+ssh://git@github.com/agsh/onvif.git#9742ea117b2d19eb31deb54cfb9e2b98f21f9d1f" = {
  name = "onvif";
  packageName = "onvif";
  version = "0.6.5";
  src = fetchgit {
    url = "ssh://git@github.com/agsh/onvif.git";
    rev = "9742ea117b2d19eb31deb54cfb9e2b98f21f9d1f";
    sha256 = "037fb1769c2f594d00eb8e96f295c33ccd480bfe2100cb15075836dbc4b62a2c";
  };
};

and it's referenced later in that file with:

(sources."onvif-git+ssh://git@github.com/agsh/onvif.git#9742ea117b2d19eb31deb54cfb9e2b98f21f9d1f" // {
  dependencies = [
    sources."xml2js-0.4.23"
    sources."xmlbuilder-11.0.1"
  ];
})

I do note that this is the only dep in the entire file using fetchgit and not fetchurl. Something?

I was seeing this issue too. I tried manually replacing instances of fetchgit with builtins.fetchGit in node-packages.nix (and removing the sha256, since builtins.fetchGit doesn't have that attribute) and that worked for me.

It's not great to have that as a manual step, this might be another reason to merge #298.

This is affecting me, I can't use github repos in any package.json.

As #298 won't happen, what about giving the user the option to enable fetchGit instead of forcing the usage of fetchgit?
