You could try the search feature in pip, 

<pre><code>$ pip search yaml
</code></pre>

which looks for packages in PyPI with yaml in the short description. That reveals various packages, including PyYaml, yamltools, and PySyck, among others (Note that <a href="http://pyyaml.org/wiki/PySyck" rel="noreferrer">PySyck docs</a> recommend using PyYaml, since syck is out of date). Now you know a specific package name, you can install it:

<pre><code>$ pip install pyyaml
</code></pre>

If you want to install python yaml system-wide in linux, you can also use a package manager, like <code>aptitude</code> or <code>yum</code>:

<pre><code>$ sudo apt-get install python-yaml
$ sudo yum install python-yaml
</code></pre>

There are three YAML capable packages. Syck (<code>pip install syck</code>) which implements the YAML 1.0 specification from 2002; PyYAML (<code>pip install pyyaml</code>) which follows the YAML 1.1 specification from 2004; and <a href="https://pypi.python.org/pypi/ruamel.yaml/" rel="nofollow noreferrer">ruamel.yaml</a> which follows the latest (YAML 1.2, from 2009) specification.

You can install the YAML 1.2 compatible package with <code>pip install ruamel.yaml</code> or if you are running a modern version of Debian/Ubuntu (or derivative) with:

<pre><code>sudo apt-get install python-ruamel.yaml

"There should be one -- and preferably only one -- obvious way to do it." So let me add another one. This one is more like "install from sources" for Debian/Ubuntu, from <a href="https://github.com/yaml/pyyaml" rel="noreferrer">https://github.com/yaml/pyyaml</a>

Install the libYAML and it's headers:

<pre><code>sudo apt-get install libyaml-dev

<a href="http://pyyaml.org/download/pyyaml" rel="noreferrer">Download</a> the pyyaml sources:

<pre><code>wget http://pyyaml.org/download/pyyaml/PyYAML-3.13.tar.gz

Install from sources, (don't forget to activate your venv):

<pre><code>. your/env/bin/activate
tar xzf PyYAML-3.13.tar.gz
cd PyYAML-3.13.tar.gz
(env)$ python setup.py install
