Vagrant: * Unknown configuration section 'disksize' - vagrant

Question

During the configuration of Vagrant environment on my machine I've received this message:
Vagrant:
* Unknown configuration section 'disksize'.
It was shown after the plugin has already been installed.
Here is the vagrantfile:
# -*- mode: ruby -*-

# The most common configuration options are documented and commented below.
# For a complete reference, please see the online documentation at

# Create a forwarded port mapping which allows access to a specific port

I've tried changing the capacity of disksize.size to a smaller size, but without success.
What could be the problem?
Thanks in advance

You need to install the plugin:
vagrant plugin install vagrant-disksize
