Silently install missing plugins?

is there something I can add to this line:

  config.vagrant.plugins = ["vagrant-timezone", "vagrant-vbguest"]

to make Vagrant install the plugin(s) if missing, without asking the user and without making them ‘vagrant up’ again?

An environment variable can be set to disable the prompting:

Thanks – I added

ENV['VAGRANT_INSTALL_LOCAL_PLUGINS'] = "true"

to the top of the Vagrantfile, and it installed the plugins without asking. But is there a way to make Vagrant continue on with the ‘vagrant up’ after installing the plugins, without user interaction?

No, after the plugins are installed Vagrant must be started again for the newly available plugins to be properly loaded.

ok thanks for your help!
