<title>Installing Home Manager</title>
|

<para>
|
||
Home Manager can be used in three primary ways:
|
||
<orderedlist>
|
||
<listitem>
|
||
<para>
|
||
Using the standalone <command>home-manager</command> tool. For platforms
|
||
other than NixOS and Darwin, this is the only available choice. It is also
|
||
recommended for people on NixOS or Darwin that want to manage their home
|
||
directory independent of the system as a whole. See
|
||
<xref linkend="sec-install-standalone"/> for instructions on how to
|
||
perform this installation.
|
||
</para>
|
||
</listitem>
|
||
<listitem>

<para>

As a module within a NixOS system configuration. This allows the user
|
||
profiles to be built together with the system when running
|
||
<command>nixos-rebuild</command>. See
|
||
<xref linkend="sec-install-nixos-module"/> for a description of this
|
||
setup.

Make sure you have a working Nix installation. If you are not using NixOS
|
||
then it may be necessary to run
|
||
</para>
|
||
<screen>
|
||
<prompt>$</prompt> <userinput>mkdir -m 0755 -p /nix/var/nix/{profiles,gcroots}/per-user/$USER</userinput>
|
||
</screen>
|
||
<para>
|
||
since Home Manager uses these directories to manage your profile
|
||
generations. On NixOS these should already be available.
|
||
</para>
|
||
<para>
|
||
Also make sure that your user is able to build and install Nix packages.
|
||
For example, you should be able to successfully run a command like
|
||
<literal>nix-instantiate '<nixpkgs>' -A hello</literal> without
|
||
having to switch to the root user. For a multi-user install of Nix this
|
||
means that your user must be covered by the
|
||
<link xlink:href="https://nixos.org/nix/manual/#conf-allowed-users"><literal>allowed-users</literal></link>
|
||
Nix option. On NixOS you can control this option using the
|
||
<link xlink:href="https://nixos.org/nixos/manual/options.html#opt-nix.allowedUsers"><literal>nix.allowedUsers</literal></link>
|
||
system option.

Add the Home Manager channel that you wish to follow. This is done by
|
||
running
|
||
</para>
|
||
<screen>
|
||
<prompt>$</prompt> <userinput>nix-channel --add https://github.com/rycee/home-manager/archive/master.tar.gz home-manager</userinput>
|

<prompt>$</prompt> <userinput>nix-channel --update</userinput>
|

</screen>
|

<para>
|
||
if you are following Nixpkgs master or an unstable channel and
|
||
</para>
|
||
<screen>
|
||
<prompt>$</prompt> <userinput>nix-channel --add https://github.com/rycee/home-manager/archive/release-19.03.tar.gz home-manager</userinput>
|

<prompt>$</prompt> <userinput>nix-channel --update</userinput>
|

</screen>
|
||
<para>
|
||
if you follow a Nixpkgs version 19.03 channel.
|
||
</para>
|
||
<para>
|
||
On NixOS you may need to log out and back in for the channel to become
|
||
available. On non-NixOS you may have to add
|
||
<programlisting language="bash">
|
||
export NIX_PATH=$HOME/.nix-defexpr/channels${NIX_PATH:+:}$NIX_PATH
|
||
</programlisting>
|
||
to your shell (see
|
||
<link xlink:href="https://github.com/NixOS/nix/issues/2033">nix#2033</link>).
|
||
</para>
|
||
</listitem>
|
||
<listitem>
|
||
<para>
|
||
Run the Home Manager installation command and create the first Home
|
||
Manager generation:
|
||
</para>
|
||
<screen>
|
||
<prompt>$</prompt> <userinput>nix-shell '<home-manager>' -A install</userinput>
|
||
</screen>
|
||
<para>
|
||
Once finished, Home Manager should be active and available in your user
|
||
environment.
|
||
</para>
|
||
</listitem>
|
||
<listitem>
|
||
<para>
|
||
If you do not plan on having Home Manager manage your shell configuration
|
||
then you must source the
|
||
</para>
|
||
<programlisting language="bash">
|
||
$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh
|
||
</programlisting>
|
||
<para>
|
||
file in your shell configuration. Unfortunately, we currently only support
|
||
POSIX.2-like shells such as
|
||
<link xlink:href="https://www.gnu.org/software/bash/">Bash</link> or
|
||
<link xlink:href="http://zsh.sourceforge.net/">Z shell</link>.
|
||
</para>
|
||
<para>
|
||
For example, if you use Bash then add
|
||
</para>
|
||
<programlisting language="bash">
|
||
. "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh"
|
||
</programlisting>
|
||
<para>
|
||
to your <literal>~/.profile</literal> file.
|
||
</para>
|
||
</listitem>
|
||
</orderedlist>
|
||
|
||
<para>
|
||
If instead of using channels you want to run Home Manager from a Git
|
||
checkout of the repository then you can use the
|
||
<literal>programs.home-manager.path</literal> option to specify the absolute
|
||
path to the repository.

|
||
Home Manager provides a NixOS module that allows you to prepare user
|
||
environments directly from the system configuration file, which often is
|
||
more convenient than using the <command>home-manager</command> tool. It also
|
||
opens up additional possibilities, for example, to automatically configure
|
||
user environments in NixOS declarative containers or on systems deployed
|
||
through NixOps.
|
||
</para>
|
||
|
||
<para>
|
||
To make the NixOS module available for use you must <option>import</option>
|
||
it into your system configuration. This is most conveniently done by adding
|
||
a Home Manager channel, for example
|
||
</para>
|
||
|
||
<screen>
|
||
<prompt>#</prompt> <userinput>nix-channel --add https://github.com/rycee/home-manager/archive/master.tar.gz home-manager</userinput>
|
||
<prompt>#</prompt> <userinput>nix-channel --update</userinput>
|
||
</screen>
|
||
|
||
<para>
|
||
if you are following Nixpkgs master or an unstable channel and
|
||
</para>
|
||
|
||
<screen>
|
||
<prompt>#</prompt> <userinput>nix-channel --add https://github.com/rycee/home-manager/archive/release-19.03.tar.gz home-manager</userinput>
|
||
<prompt>#</prompt> <userinput>nix-channel --update</userinput>
|
||
</screen>
|
||
|
||
<para>
|
||
if you follow a Nixpkgs version 19.03 channel.
|
||
</para>
|
||
|
||
<para>
|
||
It is then possible to add
|
||
</para>
|
||
|
||
<programlisting language="nix">
|
||
imports = [ <home-manager/nixos> ];
|
||
</programlisting>
|
||
|
||
<para>
|
||
to your system <filename>configuration.nix</filename> file, which will
|
||
introduce a new NixOS option called <option>home-manager.users</option>
|
||
whose type is an attribute set that maps user names to Home Manager
|
||
configurations.
|
||
</para>
|
||
|
||
<para>
|
||
For example, a NixOS configuration may include the lines
|
||
</para>
|
||
|
||
<programlisting language="nix">
|
||
users.users.eve.isNormalUser = true;
|
||
home-manager.users.eve = { pkgs, ... }: {
|
||
home.packages = [ pkgs.atool pkgs.httpie ];
|
||
programs.bash.enable = true;
|
||
};
|
||
</programlisting>
|
||
|
||
<para>
|
||
and after a <command>nixos-rebuild switch</command> the user eve's
|
||
environment should include a basic Bash configuration and the packages atool
|
||
and httpie.
|
||
</para>
|
||
|
||
<note>
|
||
<para>
|
||
By default packages will be installed to
|
||
<filename>$HOME/.nix-profile</filename> but they can be installed to
|
||
<filename>/etc/profiles</filename> if
|
||
</para>
|
||
<programlisting language="nix">
|
||
home-manager.useUserPackages = true;
|
||
</programlisting>
|
||
<para>
|
||
is added to the system configuration. This is necessary if, for example,
|
||
you wish to use <command>nixos-rebuild build-vm</command>. This option may
|
||
become the default value in the future.
