FATAL: Could not read output of 'nix-prefetch-url'

[t-a-m-e]

The command returned a message stating it was a bug, and asking to create a ticket..so here it is. I read through the previous issue, and am still struggling to get it working. The command that worked for them is not working for me. I'm working through the intro to nix tutorials, the command doesn't make sense to me even after searching for it..

Initializing
Creating nix/sources.nix
Creating nix/sources.json
Importing 'nixpkgs' ...
Adding package nixpkgs
FATAL: Could not read the output of 'nix-prefetch-url'. This is a bug. Please create a
