sometime by default in latest plone the paster command is missing,
to add paster you need to install it via buildout
so in your plone buildout add zopeskel in parts section like this:
then add this zopeskel section somewhere in buildout, i added below [instance] part like this:
# installs paster and Zopeskel
recipe = zc.recipe.egg
then rerun buildout, now you will be able to create paster commands, this paster script will be in yoru zinstance/bin/paster
hope this helps!
