# Installation¶

## Binary wheel install¶

PyNaCl ships as a binary wheel on OS X, Windows and Linux manylinux1 [1] , so all dependencies are included. Make sure you have an up-to-date pip and run:

$pip install pynacl  ## Linux source build¶ PyNaCl relies on libsodium, a portable C library. A copy is bundled with PyNaCl so to install you can run: $ pip install pynacl


If you’d prefer to use the version of libsodium provided by your distribution, you can disable the bundled copy during install by running:

\$ SODIUM_INSTALL=system pip install pynacl


Warning

Usage of the legacy easy_install command provided by setuptools is generally discouraged, and is completely unsupported in PyNaCl’s case.

 [1] manylinux1 wheels are built on a baseline linux environment based on Centos 5.11 and should work on most x86 and x86_64 glibc based linux environments.
