<title>Environment Variables</title>
|
|
|
|
<para>To use Nix, some environment variables should be set. In
|
|
particular, <envar>PATH</envar> should contain the directories
|
|
<filename><replaceable>prefix</replaceable>/bin</filename> and
|
|
<filename>~/.nix-profile/bin</filename>. The first directory contains
|
|
the Nix tools themselves, while <filename>~/.nix-profile</filename> is
|
|
a symbolic link to the current <emphasis>user environment</emphasis>
|
|
(an automatically generated package consisting of symlinks to
|
|
installed packages). The simplest way to set the required environment
|
|
variables is to include the file
|
|
<filename><replaceable>prefix</replaceable>/etc/profile.d/nix.sh</filename>
|
|
in your <filename>~/.profile</filename> (or similar), like this:</para>
|
|
|
|
<screen>
|
|
source <replaceable>prefix</replaceable>/etc/profile.d/nix.sh</screen>
