bug#44437: Best way to install package in Guix System

[Tobias Geerinckx-Rice via Bug reports for GNU Guix]

musics--- via Bug reports for GNU Guix 写道：

I changed the config.scm file, after running "sudo guix system reconfigure /etc/config.scm" it displayed: /etc/config.scm:31:6: error: network-manager-type: unbound variable

hint: Did you forget a ʻuse-modules' form?

If you're using regular Guile use-modules syntax:

 (use-modules ...
              (gnu services networking)
              ...)

Or the Guix-specific use-service-modules syntax:

 (use-service-modules ...
                      networking
                      ...)



Kind regards,

T G-R

You need to import the module that provides ‘network-manager-type’. Sometimes Guix suggests the module name in the hint, but not here. You can find out the file name with ‘guix system search network-manager’ (eventually you'll ‘just know’, or grep the source ;-) If the file name is gnu/services/networking.scm, the Guile module name is (gnu services networking). This is a rule. The latter is less verbose over time but both do the exact same thing.
