[Plone 5.2-rc2] No module named 'bbb'

[NicolasGoeddel]

Hi,

I just installed a fresh Plone 5.2-rc2 with Python 3.6 and Postgres as Relstorage. It works great, but after adding the egg 'collective.solr' I get this error:

  ...
  File "/home/bfd/plone/buildout-cache/eggs/Products.Archetypes-1.16.1-py3.6.egg/Products/Archetypes/__init__.py", line 2, in <module>
    import bbb
ModuleNotFoundError: No module named 'bbb'

This is my buildout.cfg

[buildout]
extensions =
    buildout.sanitycheck

extends =
    base.cfg
    release-5.2.0-versions.cfg

find-links +=
    http://dist.plone.org/release/5.2.0

buildout-user = user
need-sudo = no

eggs =
    Plone

    RelStorage[postgresql]
    collective.solr

#    plone.reload

develop =
#    src/my.package

[instance_relstorage]

rel-storage =
    type postgresql

[client1]

http-address = 8080

[client2]

http-address = 8081

[versions]

buildout.sanitycheck = 1.0.2
collective.recipe.backup = 4.1.0
plone.recipe.unifiedinstaller = 5.2b1

I also tried adding the following lines but these files are not available. So the installation documention seems to be outdated.

  https://raw.githubusercontent.com/collective/collective.solr/master/solr.cfg
  https://raw.githubusercontent.com/collective/collective.solr/master/solr-4.10.x.cfg

What am I missing? What am I doing wrong? What information do you need from me to help me?

With version 8.0.0a1 Plone is able to start but I don't know if it is a good idea to use an alpha version at the moment. ;-)

@NicolasGoeddel 7.0.0x is also in alpha so you don't have much of a choice right now if you want to use a recent version of Solr. We are using 8.0.0a1 in pre-production right now and it might already be a better choice than 7.x. That's just my 2c though.

[NicolasGoeddel]

I close that because it's an issue with an older version and with 8.0.0a1 it works perfectly fine.
