module: pip
short_description: Manages Python library dependencies
description:
- "Manage Python library dependencies. To use this module, one of the following keys is required: C(name)
or C(requirements)."
version_added: "0.7"
options:
name:
description:
- The name of a Python library to install or the url(bzr+,hg+,git+,svn+) of the remote package.
- This can be a list (since 2.2) and contain version specifiers (since 2.7).
version:
description:
- The version number to install of the Python library specified in the I(name) parameter.
requirements:
description:
- The path to a pip requirements file, which should be local to the remote system.
File can be specified as a relative path if using the chdir option.
virtualenv:
description:
- An optional path to a I(virtualenv) directory to install into.
It cannot be specified together with the 'executable' parameter
(added in 2.1).
If the virtualenv does not exist, it will be created before installing
packages. The optional virtualenv_site_packages, virtualenv_command,
and virtualenv_python options affect the creation of the virtualenv.
virtualenv_site_packages:
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.
type: bool
default: "no"
version_added: "1.0"
virtualenv_command:
description:
- The command or a pathname to the command to create the virtual
environment with. For example C(pyvenv), C(virtualenv),
C(virtualenv2), C(~/bin/virtualenv), C(/usr/local/bin/virtualenv).
default: virtualenv
version_added: "1.1"
virtualenv_python:
description:
- The Python executable used for creating the virtual environment.
For example C(python3.5), C(python2.7). When not specified, the
Python version used to run the ansible module is used. This parameter
should not be used when C(virtualenv_command) is using C(pyvenv) or
the C(-m venv) module.
version_added: "2.0"
state:
description:
- The state of module
- The 'forcereinstall' option is only available in Ansible 2.1 and above.
choices: [ absent, forcereinstall, latest, present ]
default: present
extra_args:
description:
- Extra arguments passed to pip.
version_added: "1.0"
editable:
description:
- Pass the editable flag.
type: bool
default: 'no'
version_added: "2.0"
chdir:
description:
- cd into this directory before running the command
version_added: "1.3"
executable:
description:
- The explicit executable or a pathname to the executable to be used to
run pip for a specific version of Python installed in the system. For
example C(pip-3.3), if there are both Python 2.7 and 3.3 installations
in the system and you want to run pip for the Python 3.3 installation.
It cannot be specified together with the 'virtualenv' parameter (added in 2.1).
By default, it will take the appropriate version for the python interpreter
use by ansible, e.g. pip3 on python 3, and pip2 or pip on python 2.
version_added: "1.3"
umask:
description:
- The system umask to apply before installing the pip package. This is
useful, for example, when installing on systems that have a very
restrictive umask by default (e.g., "0077") and you want to pip install
packages which are to be used by all users. Note that this requires you
to specify desired umask mode as an octal string, (e.g., "0022").
version_added: "2.1"
notes:
- Please note that virtualenv (U(http://www.virtualenv.org/)) must be
installed on the remote host if the virtualenv parameter is specified and
the virtualenv needs to be created.
- By default, this module will use the appropriate version of pip for the
interpreter used by ansible (e.g. pip3 when using python 3, pip2 otherwise)
requirements:
- pip
- virtualenv
- setuptools
