Buildout problem

I have a minimal buildout to illustrate my problem.

parts =

find-links =

recipe = plone.recipe.zope2instance
user = admin:admin
http-address = 8080

eggs =

The result of pip list:

pip (9.0.1)
pkg-resources (0.0.0)
setuptools (38.2.3)
wheel (0.30.0)
zc.buildout (2.9.5)

I want to install now.

Error: Wheels are not supported

I do not know how to come around this error. In "former times" buildout has downloaded a earlier version of buildout and restartet buildout. Now it starts to install wheels. What has changed and how to bypass this error?

I had the same problem recently in a travis build. Try using


It's due to an update in setuptools:

Maybe someone could be bothered with what to do (where to put this) or maybe update something (I think this happens with 'the latest installer'

No since the bugs are fixed in setuptools and zc.buildout, those are the versions working right now:


They should be added in a requirements.txt file and installed into a virtual environment with pip install -r requirements.txt.
