Vagrant with VirtualBox on Windows10: “Rsync” could not be found on your PATH

Question

I found in another forum that the local Vagrant directory is mounted as “/vagrant” via rsync. This is set in the box itself, you can check by opening

C:\Users\{your_username}\.vagrant.d\boxes\debian-VAGRANTSLASH-jessie64\8.2.2\virtualbox\Vagrantfile

and see the setting

  config.vm.synced_folder \
    ".",
    "/vagrant",
    type: "rsync"

to get around this I added the following line in my local Vagrantfile

  config.vm.synced_folder ".", "/vagrant", type: "virtualbox"

and the error was resolved
