As explained inline, we can have systems where pip is installed, but python3-venv isn't. This role is assuming that "python3 -m venv --help" indicates that you will be able to create a working venv with this command, but this is unfortunately incorrect. On Debuntu this requires the python3-venv package as well. Put in an unconditional probe for this in the workarounds, and install it if required. Change-Id: Iaa3ecd05b64af6dd9b2ee17a39bcbe6cde8686ba
Ensure pip is available
This role is intended install the requirements for the pip module on hosts.
Jobs that also wish to call pip via shell commands
directly can also use this to ensure pip is available.
However, it should be noted that calling pip is ambiguous
when supporting many platforms. On some platforms it may install the
package under the Python 2 interpreter and in others Python 3. You
should use a qualified name (pip2 or pip3) to
avoid confusion.
Role Variables
Output Variables
This variable will be set to a command appropriate for general usage with the
pipmodulevirtualenv_commandargument on the host. On Python 3 hosts this will be the inbuiltvenvmodule, on Python 2 hosts thevirtualenvpackage will be installed (this is avoided on Python 3 hosts as an unnecessary dependency).
