Vagrant is a tool for building and distributing development environments.

VagrantPlugins::Chef::Config::Base#version=

The version of Chef to install. If Chef is already installed on the
system, the installed version is compared with the requested version.
If they match, no action is taken. If they do not match, version of
the value specified in this attribute will be installed over top of
the existing version (a warning will be displayed).

You can also specify "latest" (default), which will install the latest
version of Chef on the system. In this case, Chef will use whatever
version is on the system. To force the newest version of Chef to be
installed on every provision, set the {#install} option to "force".
