How do I install the yaml package for Python?

I have a Python program that uses YAML. I attempted to install it on a new server using

pip install yaml
and it returns the following:

$ sudo pip install yaml
Downloading/unpacking yaml
Could not find any downloads that satisfy the requirement yaml
No distributions at all found for yaml
Storing complete log in /home/pa/.pip/pip.log

How do I install the yaml package for Python? I'm running Python 2.7.

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including PyYaml, yamltools, and PySyck, among others (Note that PySyck docs recommend using PyYaml, since syck is out of date).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
