vagrant up時のエラー（unexpected tIDENTIFIER）の対応方法

Question

環境
・Windows10
・Vagrant 2.2.2
・VirtualBox 5.2.22
・CentOS 6.6（BOX：https://app.vagrantup.com/bento/boxes/centos-6.6）

上記の環境で、vagrant initで初期化し、vagrantfileが作成されるところまでは問題なくきたのですが、
そこからvagrant upを実行すると

Vagrant failed to initialize at a very early stage:

There is a syntax error in the following Vagrantfile. The syntax error
message is reproduced below for convenience:

c:/Vagrant/centos66/Vagrantfile:23: syntax error, unexpected tIDENTIFIER, expecting keyword_end

accessing "localhost:8080" will access port 80 on

というエラーが出てしまいます。

vagrantfileの中身は下記になっており、初期状態から34行目のコメントアウト解除のみ変更しています。

-- mode: ruby --

vi: set ft=ruby :

All Vagrant configuration is done below. The "2" in Vagrant.configure

configures the configuration version (we support older styles for

backwards compatibility). Please don't change it unless you know what

you're doing.

Vagrant.configure("2") do |config|

The most common configuration options are documented and commented below.

For a complete reference, please see the online documentation at

https://docs.vagrantup.com.

Every Vagrant development environment requires a box. You can search for

boxes at https://vagrantcloud.com/search.

config.vm.box = "bento/centos-6.6"

The url from where the 'config.vm.box' box will be fetched if it

doesn't already exist on the user's system.

config.vm.box_url = ""

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

within the machine from a port on the host machine. In the example below,

accessing "localhost:8080" will access port 80 on the guest machine.

NOTE: This will enable public access to the opened port

config.vm.network "forwarded_port", guest: 80, host: 8080

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

within the machine from a port on the host machine and only allow access

via 127.0.0.1 to disable public access

config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

Create a private network, which allows host-only access to the machine

using a specific IP.

config.vm.network "private_network", ip: "192.168.33.10"

Create a public network, which generally matched to bridged network.

Bridged networks make the machine appear as another physical device on

your network.

config.vm.network "public_network"

Share an additional folder to the guest VM. The first argument is

the path on the host to the actual folder. The second argument is

the path on the guest to mount the folder. And the optional third

argument is a set of non-required options.

config.vm.synced_folder "../data", "/vagrant_data"

Provider-specific configuration so you can fine-tune various

backing providers for Vagrant. These expose provider-specific options.

Example for VirtualBox:

config.vm.provider "virtualbox" do |vb|

# Display the VirtualBox GUI when booting the machine

vb.gui = true

# Customize the amount of memory on the VM:

vb.memory = "1024"

end

View the documentation for the provider you are using for more

information on available options.

Enable provisioning with a shell script. Additional provisioners such as

Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the

documentation for more information about their specific syntax and use.

config.vm.provision "shell", inline: <<-SHELL

apt-get update

apt-get install -y apache2

SHELL

end

どうかご回答よろしくお願いいたします。

vagrantfileを改めて見ていたところ、

config.vm.box_url = ""

で、URLが記載されておらず""になっていたので、ここをURL（https://app.vagrantup.com/bento/boxes/centos-6.6）に置き換えてvagrant upを実施し直したところエラーが解消されました。
