pipx: fix state=latest w/ install_deps=true (#6303) 
* pipx and pipx_info: Document that modules require pipx 0.16.2.1 or above

Since their introduction, these modules rely on 'pipx list --json' to
return machine-readable output about installed pipx applications. That
functionality was introduced in 0.16.2, along with a critical bug fix
(invalid json) in 0.16.2.1.

* pipx: fix state=latest with install_deps=true

"pipx upgrade" stopped supporting the "--include-deps" option
("install_deps" in the ansible module) in pipx 0.15
(https://pypa.github.io/pipx/changelog/#01500).

The lack of support causes the pipx module to fail if attempting to use
state=latest with install_deps, since the parameter is passed to both
pipx install (fine) and pipx upgrade (fails).

options:
state:
type: str
choices: [present, absent, install, uninstall, uninstall_all, inject, upgrade, upgrade_all, reinstall, reinstall_all, latest]
default: install
description:
- Desired state for the application.
- The states C(present) and C(absent) are aliases to C(install) and C(uninstall), respectively.
- The state C(latest) is equivalent to executing the task twice, with state C(install) and then C(upgrade).
It was added in community.general 5.5.0.
name:
type: str
description:
- >
The name of the application to be installed. It must to be a simple package name.
For passing package specifications or installing from URLs or directories,
please use the I(source) option.
source:
type: str
description:
- >
If the application source, such as a package with version specifier, or an URL,
directory or any other accepted specification. See C(pipx) documentation for more details.
- When specified, the C(pipx) command will use I(source) instead of I(name).
install_apps:
description:
- Add apps from the injected packages.
- Only used when I(state=inject).
type: bool
default: false
version_added: 6.5.0
install_deps:
description:
- Include applications of dependent packages.
- Only used when I(state=install), I(state=latest), or I(state=inject).
type: bool
default: false
inject_packages:
description:
- Packages to be injected into an existing virtual environment.
- Only used when I(state=inject).
type: list
elements: str
force:
description:
- Force modification of the application's virtual environment. See C(pipx) for details.
- Only used when I(state=install), I(state=upgrade), I(state=upgrade_all), I(state=latest), or I(state=inject).
type: bool
default: false
include_injected:
description:
- Upgrade the injected packages along with the application.
- Only used when I(state=upgrade), I(state=upgrade_all), or I(state=latest).
- This is used with I(state=upgrade) and I(state=latest) since community.general 6.6.0.
type: bool
default: false
index_url:
description:
- Base URL of Python Package Index.
- Only used when I(state=install), I(state=upgrade), I(state=latest), or I(state=inject).
type: str
python:
description:
- Python version to be used when creating the application virtual environment. Must be 3.6+.
- Only used when I(state=install), I(state=latest), I(state=reinstall), or I(state=reinstall_all).
type: str
system_site_packages:
description:
- Give application virtual environment access to the system site-packages directory.
- Only used when I(state=install) or I(state=latest).
type: bool
default: false
version_added: 6.6.0
executable:
description:
- Path to the C(pipx) installed in the system.
- >
If not specified, the module will use C(python -m pipx) to run the tool,
using the same Python interpreter as ansible itself.
type: path
editable:
description:
- Install the project in editable mode.
type: bool
default: false
version_added: 4.6.0
pip_args:
description:
- Arbitrary arguments to pass directly to C(pip).
type: str
version_added: 4.6.0
notes:
- This module does not install the C(pipx) python package, however that can be easily done with the module M(ansible.builtin.pip).
- This module does not require C(pipx) to be in the shell C(PATH), but it must be loadable by Python as a module.
- >
This module will honor C(pipx) environment variables such as but not limited to C(PIPX_HOME) and C(PIPX_BIN_DIR)
passed using the R(environment Ansible keyword, playbooks_environment).
- This module requires C(pipx) version 0.16.2.1 or above.
- Please note that C(pipx) requires Python 3.6 or above.
- >
This first implementation does not verify whether a specified version constraint has been installed or not.
Hence, when using version operators, C(pipx) module will always try to execute the operation,
even when the application was previously installed.
This feature will be added in the future.
- See also the C(pipx) documentation at U(https://pypa.github.io/pipx/).
