<title>Installing a Binary Distribution</title>
|
||
|
||
<para>The easiest way to install Nix is to run the following command:
|
||
|
||
<screen>
|
||
$ bash <(curl https://nixos.org/nix/install)
|
||
</screen>
|
||
|
||
This will perform a single-user installation of Nix, meaning that
|
||
<filename>/nix</filename> is owned by the invoking user. You should
|
||
run this under your usual user account, <emphasis>not</emphasis> as
|
||
root. The script will invoke <command>sudo</command> to create
|
||
<filename>/nix</filename> if it doesn’t already exist. If you don’t
|
||
have <command>sudo</command>, you should manually create
|
||
<command>/nix</command> first as root:
|
||
|
||
<screen>
|
||
$ mkdir /nix
|
||
$ chown alice /nix
|
||
</screen>
|
||
|
||
</para>
|
||
|
||
<para>You can also manually download and install a binary package.
|
||
Binary packages of the latest stable release are available for Fedora,
|
||
Debian, Ubuntu, Mac OS X and various other systems from the <link
|
||
xlink:href="http://nixos.org/nix/download.html">Nix homepage</link>.
|
||
You can also get builds of the latest development release from our
|
||
<link
|
||
xlink:href="http://hydra.nixos.org/job/nix/master/release/latest-finished#tabs-constituents">continuous
|
||
build system</link>.</para>
|
||
|
||
<para>For Fedora, RPM packages are available. These can be installed
|
||
or upgraded using <command>rpm -U</command>. For example,
|
||
|
||
<screen>
|
||
$ rpm -U nix-1.7-1.i386.rpm</screen>
|
||
|
||
</para>
|
||
|
||
<para>For Debian and Ubuntu, you can download a Deb package and
|
||
install it like this:
|
||
|
||
<screen>
|
||
$ dpkg -i nix_1.7-1_amd64.deb</screen>
|
||
|
||
</para>
|
||
|
||
<para>For other platforms, including Mac OS X (Darwin), FreeBSD and
|
||
other Linux distributions, you can download a binary tarball that
|
||
contains Nix and all its dependencies. (This is what the install
|
||
script at <uri>https://nixos.org/nix/install</uri> uses.) You should
|
||
unpack it somewhere (e.g. in <filename>/tmp</filename>), and then run
|
||
the script named <command>install</command> inside the binary tarball:
|
||
|
||
<screen>
|
||
alice$ cd /tmp
|
||
alice$ tar xfj nix-1.7-x86_64-darwin.tar.bz2
|
||
alice$ cd nix-1.7-x86_64-darwin
|
||
alice$ ./install
|
||
</screen>
|
||
|
||
</para>
|
||
|
||
<para>Nix can be uninstalled using <command>rpm -e nix</command> or
|
||
<command>dpkg -r nix</command> on RPM- and Dpkg-based systems,
|
||
respectively. After this you should manually remove the Nix store and
|
||
other auxiliary data, if desired:
|
||
|
||
<screen>
|
||
$ rm -rf /nix</screen>
|
||
|
||
</para>
