»Minimum Vagrant Version

A set of Vagrant version requirements can be specified in the Vagrantfile to enforce that people use a specific version of Vagrant with a Vagrantfile. This can help with compatibility issues that may otherwise arise from using a too old or too new Vagrant version with a Vagrantfile.

Vagrant version requirements should be specified at the top of a Vagrantfile with the Vagrant.require_version helper:

Vagrant.require_version ">= 1.3.5"

In the case above, the Vagrantfile will only load if the version loading it is Vagrant 1.3.5 or greater.

Multiple requirements can be specified as well:

Vagrant.require_version ">= 1.3.5", "< 1.4.0"
