However, libuv derivation seems to have conflict. I do not know how to override this and continue building. ubuntu: 17.04 nix-env (Nix) 1.11.15 03pre118668.
Your output doesn't show the actual error. That would be above, or you can retrieve it by Using sandboxing might help to avoid (many) errors if you build yourself, but I understand it's harder to set up on non-NixOS...
From I guess the build was done but it failed in the tests. Apparently those tests were known to fail randomly on Darwin before...
Actually, there is some issue with my network. However, if I try to build inside an lxc container, then it builds fine.
