vagrant 中的同步文件夹未实时同步

Question

我正在 vagrant 机器中设置一个同步文件夹，如下面的 cmd dump 所示，并期望每当我在主机上更新此文件夹中的文件时，更新也会反映在来宾机器中，但这是没有发生。

这是转储和它没有发生的证据（我创建了一个示例文件并通过将其中的文本从 test1 更改为 test2 来修改它）：

mypc:~ user$ cd Projects/synctest/
mypc:synctest user$ ls
Vagrantfile
mypc:synctest user$ cat Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  # always use Vagrants insecure key
  config.ssh.insert_key = false

  # Setup box
  config.vm.box = "coreos-stable"

  # Setup shared folder
  config.vm.synced_folder ".", "/vagrant"

  # Setup memory usage
  config.vm.provider "virtualbox" do |v|
    v.memory = 2048
  end

  # Define `dev` vm
  config.vm.define :dev do |dev|
  end

  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
  end

end
mypc:synctest user$ echo "test1" > test.txt
mypc:synctest user$ cat test.txt
test1
mypc:synctest user$ vagrant up

它甚至应该实时同步吗？如果是，为什么不同步？

编辑：OS X 10.8.5、VirtualBox、coreos 框。

在您的 Vagrantfile 中，同步文件夹类型默认为 vboxsf，但是，在 vagrant up stdout 中，它显示 rsync 类型，我认为您需要在配置文件中修复它。

假设您使用的是 rsync 类型，您应该在 Vagrantfile

中包含以下内容

Vagrant.configure("2") do |config|
  config.vm.synced_folder ".", "/vagrant", type: "rsync",
    rsync__exclude: ".git/"
end

NOTE: By default, rsync__auto is set to true, which means rsync-auto will watch and automatically sync this folder.

运行 vagrant rsync-auto 并且目录应该在主机和来宾之间同步。

有关详细信息，请参阅 vagrant docs。
