我已经配置了Vagrant（1.7.4），使用最新版本的VirtualBox（5.0.16 r105871）在OS X（10.11.4）上，并使用最新的ubuntu/trusty64 box版本（v20160323.0.0）进行默认配置，与此同时我的虚拟机也安装了匹配版本的guest additions。但是我似乎无法使共享目录/vagrant正常工作。在虚拟机中，/vagrant/目录是存在的，但是如果我在其上运行ls命令，它完全是空的。如果我在其中创建一个文件，它会出现在/vagrant目录下的虚拟机中，但不会同步回我本地的项目文件夹中，并且在重新启动后会消失。VirtualBox GUI显示了共享文件夹：

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

config.vm.box = "ubuntu/trusty64"
# Disable automatic box update checking. If you disable this, then
# boxes will only be checked for updates when the user runs
# `vagrant box outdated`. This is not recommended.
# config.vm.box_check_update = false
# 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: "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.
# Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
# such as FTP and Heroku are also available. See the documentation at
# https://docs.vagrantup.com/v2/push/atlas.html for more information.
# config.push.define "atlas" do |push|
# push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"
# end
# 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
# sudo apt-get update
# sudo apt-get install -y apache2

vagrant up --debug启动计算机并查看输出以查看与同步文件夹相关的任何问题，会发生什么情况？您还可以将此信息输出到文件以进行 grep/搜索：vagrant up --debug > vagrantlog.txt。 - Brian Brownton`==> default: Mounting shared folders...` `default: /vagrant => /Users/defectivebit/Code/md-wellness-apps`我在一个新目录中尝试了一下，并确保删除了.vagrant目录，但仍然得到相同的结果。 - user4493402
