The python interpreter to use to install twine if it is not already
|
||||
installed. Set it to "python3" to use python 3, for example.

**Output Variables**
|

|
||||
.. zuul:rolevar:: twine_excutable
|
||||
:default: twine
|
||||
|
||||
After running this role, ``twine_executable`` will be set as the path
|
||||
to a valid ``twine``.
|
||||
|
||||
At role runtime, look for an existing ``twine`` at this specific
|
||||
path. Note the default (``twine``) effectively means to find tox in
|
||||
the current ``$PATH``. For example, if your base image
|
||||
pre-installs twine in an out-of-path environment, set this so the
|
||||
role does not attempt to install the user version.
