pip install pyyaml  If you don t have pip  run easy install pip to install pip  which is the go-to package installer - Why use pip over easy install    If you prefer to stick with easy install  then easy install pyyaml

You could try the search feature in pip      pip search yaml   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 including PyYaml  yamltools  and PySyck  among others  Note that PySyck docs recommend using PyYaml  since syck is out of date    Now you know a specific package name  you can install it     pip install pyyaml   If you want to install python yaml system-wide in linux  you can also use a package manager  like aptitude or yum     sudo apt-get install python-yaml   sudo yum install python-yaml

There are three YAML capable packages  Syck  pip install syck  which implements the YAML 1 0 specification from 2002  PyYAML  pip install pyyaml  which follows the YAML 1 1 specification from 2004  and ruamel yaml which follows the latest  YAML 1 2  from 2009  specification   You can install the YAML 1 2 compatible package with pip install ruamel yaml or if you are running a modern version of Debian Ubuntu  or derivative  with   sudo apt-get install python-ruamel yaml

Use strictyaml instead  If you have the luxury of creating the yaml file yourself  or if you don t require any of these features of regular yaml  I recommend using strictyaml instead of the standard pyyaml package   In short  default yaml has some serious flaws in terms of security  interface  and predictability  strictyaml is a subset of the yaml spec that does not have those issues  and is better documented     You can read more about the problems with regular yaml here  OPINION  strictyaml should be the default implementation of yaml and the old yaml spec should be obsoleted

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 https   github com yaml pyyaml  Install the libYAML and it s headers   sudo apt-get install libyaml-dev   Download the pyyaml sources   wget http   pyyaml org download pyyaml PyYAML-3 13 tar gz   Install from sources   don t forget to activate your venv      your env bin activate tar xzf PyYAML-3 13 tar gz cd PyYAML-3 13 tar gz  env   python setup py install  env   python setup py test

Update  Nowadays installing is done with pip  but libyaml is still required to build the C extension  on mac    brew install libyaml python -m pip install pyyaml     Outdated method   For MacOSX  mavericks   the following seems to work   brew install libyaml sudo python -m easy install pyyaml
