[Nix-dev] Rust: "error: failed to load source for a dependency on ..."

[stewart mackenzie]

Hi,

I've `sudo nixos-rebuild --upgrade switch` 'ed and things stopped working.

steps to reproduce:

$ nix-build  --argstr debug true --argstr cache
$(./support/buildCache.sh)   -A components.nucleus_find_contract

(this command currently won't work on HEAD as

Please note there is no mention git repositories in the Cargo.toml
file, which seems to be the common source of this error on nix.

Does someone know what's going on with this error?
