I’m trying to install Plone on my MacBook (MacOS Sequoia 15.1.1) using the Plone manual, but get errors.
„Install Plone with Buildout“ (Install Plone with Buildout — Plone Documentation v6)
In Step „Run buildout“ (Command: bin/buildout) this error occurs:
While:
Installing.
Getting section instance.
Initializing section instance.
Installing recipe plone.recipe.zope2instance.
Getting distribution for 'zope.interface==7.1.1'.
An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

How can I avoid this and go on with the installation?
