If you have Nix installed on your machine, this build and
all its dependencies can be unpacked into your local Nix
store by doing:
$ gunzip < [% filename %] | nix-store --import
or to download and unpack in one command:
$ curl [% uri %] | gunzip | nix-store --import
The package can then be found in the path [%
product.path %]. You’ll probably also want to do
$ nix-env -i [% product.path %]
to actually install the package in your Nix user environment.
If you get the error message “imported
archive lacks a signature”, you should make sure that you have
sufficient access rights to the Nix store, e.g., run the
command as root.
