# Summary: Display an installed Python version
|
|
# Usage: pyenv installed [<version>]
|
|
#
|
|
# Displays the installed Python version, searching for shortcuts if necessary.
|
|
# If no version is given, `pyenv installed' displays the latest installed version.
|
|
# If version is `system`, `system` will be returned if an installed system Python can be found.
|
|
# If version is `latest`, the latest installed Python version will be returned (3.12.3).
|
|
# If version is `3`, the latest installed Python version of this major version will be returned (3.12.3).
|
|
# If version is `12` or `3.12`, the latest installed patch of this minor version will be returned (3.12.3).
|
|
# If version is `3.12.3`, the same version will be returned if that patch version is installed (3.12.3).
|
|
# If version is not found or no versions are installed, an error message will be returned with an error code.
