Hi, learning nix etc using nix.dev and ran into this issue when executing

    FATAL: Could not read the output of 'nix-prefetch-url'. This is a bug. Please create a

Hi @rscorer, thanks for the report. Does this happen consistently? What happens if you run the failing command?

$ nix-prefetch-url --unpack https://github.com/nixos/nixpkgs/archive/20f65b86b6485decb43c5498780c223571dd56ef.tar.gz --name 20f65b86b6485decb43c5498780c223571dd56ef.tar.gz

When I remember to delete the local ./nix folder, it happens each time - and I tried various nixOS versions too, all with the same result...

# nix-prefetch-url --unpack https://github.com/nixos/nixpkgs/archive/20f65b86b6485decb43c5498780c223571dd56ef.tar.gz --name 20f65b86b6485decb43c5498780c223571dd56ef.tar.gz

Contents of the ./nix folder - maybe this shows how far your tool got?

@rscorer thanks, I think it might be an issue with the environment set up by nix-shell. Can you try to run the niv command outside of the nix-shell (after having wiped the nix/ folder of course, good point)?

$ $(nix-shell -p niv --run "which niv") init --nixpkgs nixos/nixpkgs --nixpkgs-branch nixos-23.11

Hi there, I was also getting this too. Running init as described above doesn't change the contents of sources.json. I'm on NixOS, also in a nix shell, using nixpkgs 23.11.

sources.json

Seems like the root cause is that our shell.nix sets LD_LIBRARY_PATH explicitly, in order to enable some linking of Rust and C++ deps. This seemed to have prevented niv from finding GLIBCXX. Running e.g. LD_LIBRARY_PATH= niv update rust-overlay works.

The same error "Could not read the output of 'nix-prefetch-url'" appeared today, after upgrade my NixOS to 24.11 version:

  Thanks! I'll buy you a beer.

Looks like it's trying to call the command w/o space between nix-prefetch-url and --update.
