Install Plone. Buildout now includes 'buildout-versions' (and part of the older 'buildout.dumppickedversions') [closed]

Question

I have this warning during installation plone:

$ bin/buildout
While:
  Installing.
  Loading extensions.
Error: Buildout now includes 'buildout-versions' (and part of the older 'buildout.dumppickedversions').
Remove the extension from your configuration and look at the 'show-picked-versions' option in buildout's documentation.

How to fix it?

Answer 1

If you are using Buildout 2.x or higher, remove buildout.dumppickedversions from extensions e.g.:

[buildout]
extensions =
# We don't need this in 2.x:
# buildout.dumppickedversions

Or use Buildout 1.7.x:

$ curl -O https://raw.github.com/buildout/buildout/1/bootstrap/bootstrap.py
$ bin/python bootstrap.py
