yarn2nix is using lib.importJSON which isn't allowed on Hydra #83

This line: https://github.com/moretea/yarn2nix/blob/master/default.nix#L149 Doesn't evaluate on hydra because it uses import-from-derivation to function.
It's only used to extract the pname and the version field. Would be nice to allow the user to provide these manually to remove the impurity from the build.

Created https://github.com/moretea/yarn2nix/pull/84 to demonstrate the issue

There might be some more issues with evaluation in Hydra but IFD shouldn't be a problem as shown in #84. All the cool features of yarn2nix depend on IFD but it's usable without.
