要共享目录，请将此添加到你的配置中。config.vm.synced_folder "host/relative/path", "/guest/absolute/path" 。下面是一个完整配置文件中的例子。
Vagrant.configure(2) do |config|
# note that you can have this config multiple times but
# it should only be used for source code since there is
# heavy performance penalty on heavy I/O such as database files
# first path is the host's path, which can by absolute
# or relative to project's root directory
# second path is the guest path, and it must be absolute.
# It will always be created if it does not exist.
config.vm.synced_folder ".", "/vagrant"
config.vm.synced_folder "./some/dir/one", "/one", create:true
config.vm.synced_folder "./some/dir/two", "/two", create:true
# note that you can also add type. NFS is the faster
# bidirectional file syncing. In order for this to work,
# the host machine must have nfsd installed. It comes
# preinstalled on OSX and is a simple package install on Linux
config.vm.synced_folder "." "/vagrant", type: "nfs"
# owner/group
config.vm.synced_folder "." "/vagrant", owner: "root", group: "root"
end
# To reconfigure the guest machine, vagrant reload must be run.
# This halts the machine and starts it up again with
# the new configuration.
# It skips the initial step to clone the box since it is
# already created.
vagrant reload
