例如,在根目录下,当我键入：

curl http://google.com

它失败了消息：

curl: (6) Couldn't resolve host 'google.com'

我不知道是否是防火墙设置,尽管据我所知,我还没有为端口80或其他端口创建任何防火墙规则.

这是我的Vagrantfile的相关部分.如果有任何其他信息,我可以提供,请让我知道在评论：

Vagrant.configure("2") do |config|
  # All Vagrant configuration is done here. The most common configuration
  # options are documented and commented below. For a complete reference,# please see the online documentation at vagrantup.com.
 
 
  # Let Vagrant manage the hostname at boot

  # 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.
  # config.vm.network :forwarded_port,guest: 80,host: 8080
 
  # Create a private network,which allows host-only access to the machine
  # using a specific IP.
  config.vm.network :private_network,ip: "10.0.0.10"
 
  # 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
 
  # Create a public network with a given hardware address.  You can

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