module: easy_install
short_description: Installs Python libraries
description:
- Installs Python libraries, optionally in a I(virtualenv)
version_added: "0.7"
options:
name:
description:
- A Python library name
required: true
default: null
aliases: []
virtualenv:
description:
- an optional I(virtualenv) directory path to install into. If the
I(virtualenv) does not exist, it is created automatically
required: false
default: null
virtualenv_site_packages:
version_added: "1.1"
description:
- Whether the virtual environment will inherit packages from the
global site-packages directory. Note that if this setting is
changed on an already existing virtual environment it will not
have any effect, the environment must be deleted and newly
created.
required: false
default: "no"
choices: [ "yes", "no" ]
virtualenv_command:
version_added: "1.1"
description:
- The command to create the virtual environment with. For example
C(pyvenv), C(virtualenv), C(virtualenv2).
required: false
default: virtualenv
executable:
description:
- The explicit executable or a pathname to the executable to be used to
run easy_install for a specific version of Python installed in the
system. For example C(easy_install-3.3), if there are both Python 2.7
and 3.3 installations in the system and you want to run easy_install
for the Python 3.3 installation.
version_added: "1.3"
required: false
default: null
state:
version_added: "2.0"
description:
- The desired state of the library. C(latest) ensures that the latest version is installed.
required: false
choices: [present, latest]
default: present
notes:
- Please note that the M(easy_install) module can only install Python
libraries. Thus this module is not able to remove libraries. It is
generally recommended to use the M(pip) module which you can first install
using M(easy_install).
- Also note that I(virtualenv) must be installed on the remote host if the
C(virtualenv) parameter is specified.
requirements: [ "virtualenv" ]

# Examples from Ansible Playbooks
