pip – Manages Python library dependencies

Synopsis

  • Manage Python library dependencies. To use this module, one of the following keys is required: name or requirements.

Requirements

The below requirements are needed on the host that executes this module.

  • pip
  • virtualenv
  • setuptools

Parameters

Parameter Choices/Defaults Comments
chdir
path
cd into this directory before running the command
editable
boolean
    Choices:
  • no ←
  • yes
Pass the editable flag.
executable
path
The explicit executable or pathname for the pip executable, if different from the Ansible Python interpreter. For example 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.
Mutually exclusive with virtualenv (added in 2.1).
Does not affect the Ansible Python interpreter.
The setuptools package must be installed for both the Ansible Python interpreter and for the version of Python specified by this option.
extra_args
string
Extra arguments passed to pip.
name
list
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).
requirements
string
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.
state
string
    Choices:
  • absent
  • forcereinstall
  • latest
  • present ←
The state of module
The 'forcereinstall' option is only available in Ansible 2.1 and above.
umask
string
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
string
The version number to install of the Python library specified in the name parameter.
virtualenv
path
An optional path to a 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_command
path
Default:
"virtualenv"
The command or a pathname to the command to create the virtual environment with. For example pyvenv, virtualenv, virtualenv2, ~/bin/virtualenv, /usr/local/bin/virtualenv.
virtualenv_python
string
The Python executable used for creating the virtual environment. For example python3.5, python2.7. When not specified, the Python version used to run the ansible module is used. This parameter should not be used when virtualenv_command is using pyvenv or the -m venv module.
virtualenv_site_packages
boolean
    Choices:
  • no ←
  • yes
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.

Notes

Note

  • The virtualenv (http://www.virtualenv.org/) must be installed on the remote host if the virtualenv parameter is specified and the virtualenv needs to be created.
  • Although it executes using the Ansible Python interpreter, the pip module shells out to run the actual pip command, so it can use any pip version you specify with executable. By default, it uses the pip version for the Ansible Python interpreter. For example, pip3 on python 3, and pip2 or pip on python 2.
  • The interpreter used by Ansible (see ansible_python_interpreter) requires the setuptools package, regardless of the version of pip set with the executable option.
