error: An existing package already provides the following file:
$(nix build --no-link --print-out-paths ${flake1Dir}"#default.out")/bin/hello
This is the conflicting file from the new package:
$(nix build --no-link --print-out-paths ${flake2Dir}"#default.out")/bin/hello
To remove the existing package:
nix profile remove path:${flake1Dir}
The new package can also be installed next to the existing one by assigning a different priority.
The conflicting packages have a priority of 5.
To prioritise the new package:
nix profile install path:${flake2Dir} --priority 4
To prioritise the existing package:
nix profile install path:${flake2Dir} --priority 6
