Pip Operations

Manage pip (python) packages. Compatible globally or inside a virtualenv (virtual environment).

pip.packages

Install/remove/update pip packages.

pip.packages(
    packages=None, present=True, latest=False, requirements=None, pip='pip', virtualenv=None,
    virtualenv_kwargs=None, extra_install_args=None,
)

• packages: list of packages to ensure
• present: whether the packages should be installed
• latest: whether to upgrade packages without a specified version
• requirements: location of requirements file to install/uninstall
• pip: name or path of the pip directory to use
• virtualenv: root directory of virtualenv to work in
• virtualenv_kwargs: dictionary of arguments to pass to pip.virtualenv
• extra_install_args: additional arguments to the pip install command

Virtualenv:

This will be created if it does not exist already. virtualenv_kwargs will be passed to pip.virtualenv which can be used to control how the env is created.

Versions:

Package versions can be pinned like pip: <pkg>==<version>.

Example:

pip.packages(
    name='Install pyinfra into a virtualenv',
    packages=['pyinfra'],
    virtualenv='/usr/local/bin/venv',
)

pip.venv

Add/remove Python virtualenvs.

pip.venv(path, python=None, site_packages=False, always_copy=False, present=True)

• python: python interpreter to use
• site_packages: give access to the global site-packages
• always_copy: always copy files rather than symlinking
• present: whether the virtualenv should exist

Example:

pip.venv(
    name='Create a virtualenv',
    path='/usr/local/bin/venv',
)

pip.virtualenv

Add/remove Python virtualenvs.

pip.virtualenv(path, python=None, venv=False, site_packages=False, always_copy=False, present=True)

• python: python interpreter to use
• venv: use standard venv module instead of virtualenv
• site_packages: give access to the global site-packages
• always_copy: always copy files rather than symlinking
• present: whether the virtualenv should exist

Example:

pip.virtualenv(
    name='Create a virtualenv',
    path='/usr/local/bin/venv',
)
