Uninstall fails on fresh install

[schwa]

Testing nix-darwin and now trying to uninstall via

nix-build https://github.com/LnL7/nix-darwin/archive/master.tar
.gz -A uninstaller

And getting this error:

error:

Try this instead:

$ nix --extra-experimental-features "nix-command flakes" run nix-darwin#darwin-uninstaller

I just had the same issue.
Except, not a fresh install. I was using it for a while and something broke.
The same uninstall command wouldn't work for me.

This one does..
