Failed installing add-ons


I failed to install Products.PloneGetPaid on Plone 5.2. Here is what I did:

$ cd ~/Plone/zinstance

$ git clone

Add to buildout.cfg:
parts += mrbob

recipe = zc.recipe.egg
eggs =

$ cd Products.PloneGetPaid

$ ../bin/mrbob -O bobtemplates.plone:addon

$ bin/buildout -c develop.cfg

An internal error occurred due to a bug in either zc.buildout or in a

Can anyone help me fix this?

No indication that PloneGetPaid is Python 3 compatible.

PGP is EOL-ware. I wouldn't bother with it, unless you want to torture yourself with ancient code etc. The BlueDynamics folks have their, looks compatible but I've no experience with it. Good luck!
