Home manager installation failed

Help

Hi,
I add home manager configuration to the configuration.nix. Unfortunately, after reboot, I did not get the home-manager command.

$ diff /etc/nixos/configuration.nix.orginal /etc/nixos/configuration.nix.home-manager

$ sudo nano /etc/nixos/configuration.nix
$ sudo nixos-rebuild dry-build
$ sudo nixos-rebuild switch

What did I do wrong?

This gives you the home-manager functionality for your user, but not the command. Whenever you rebuild your system, it will also take care of the home-manager stuff.
If you additionally want the home-manager command, you have to list it in the installed packages.

Thank you, How can I immediately see the effect off changing dotfiles in configuratation.nix rather than after rebooting?

sudo nixos-rebuild switch should have an immediate effect.

Thank you, it works.
