我有以下错误：

Vagrant was unable to mount VirtualBox shared folders. This is usually because the filesystem “vboxsf” is not available. This
filesystem is made available via the VirtualBox Guest Additions and
kernel module. Please verify that these guest additions are properly
installed in the guest. This is not a bug in Vagrant and is usually
caused by a faulty Vagrant box. For context, the command attempted
was:

id -u vagrant

The error output from the command was:

id: ‘vagrant’: no such user

所以我试着寻找解决方案.我看过很多人说需要一个特殊的vbguest vagrant插件然后运行vagrant并且在ssh中应该修改另外的vbguest.

所以我做了以下步骤：

$vagrant plugin install vagrant-vbguest
然后添加了插件：

Installing the ‘vagrant-vbguest’ plugin. This can take a few
minutes… Installed the plugin ‘vagrant-vbguest (0.13.0)’!

$vagrant up

$vagrant ssh

$sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions /usr/lib / VBoxGuestAdditions
这不打印任何消息,所以我认为这是正确的.
然后我重新加载了流浪汉.

$vagrant reload

不幸的是,我又错了.

当然,当我删除流浪者并再次运行流浪汉并从草图重新加载时,我尝试了这种情况,但同样的问题.
是的,我也尝试过vagrant-hostmanager插件(这是在yii文档中,但同样的问题)

这是我的流浪文件,也许它对你有用.

require 'fileutils'

我的流浪汉版本是1.9.1,我的Virtualbox版本是5.1.14 r112924(最新的)

somebady有同样的问题吗？我应该采取哪些其他步骤来解决这个问题？

解决方法:

它对我来说是5.1.18.

https://www.virtualbox.org/wiki/Changelog 5.1.18修正了以下看似相关的问题：

>共享文件夹：固定不区分大小写的文件名访问(5.1.16
回归;仅限Windows用户; bug#16549)
>共享文件夹：已修复
访问长路径(5.1.16回归;仅限Windows客户;错误

14651,#16564)
