有时我得到新创build的文件，我无法访问，虽然我可以列出他们在控制台。 我的Vagrant file包含这个synced_folder设置：
config.vm.synced_folder "/home/ulkas/Develop/beauty/Beautyportal", "/vagrant/Beautyportal", owner: "vagrant", group: "vagrant", :mount_options => ['dmode=777', 'fmode=777']
它发生时，我创build/修改主机以及在客人的文件，他们只是变得无法访问：
cannot access GuzzleStreamWrapper.php: No such file or directory
什么是值得的是我可以列出他们在控制台，但没有权限（看起来像安装问题）：
vagrant@precise64:/vagrant/Beautyportal/vendor/guzzlehttp/streams/src$ ls -al ls: cannot access functions.php: No such file or directory ls: cannot access NoSeekStream.php: No such file or directory ls: cannot access LazyOpenStream.php: No such file or directory ls: cannot access MetadataStreamInterface.php: No such file or directory ls: cannot access StreamInterface.php: No such file or directory ls: cannot access LimitStream.php: No such file or directory ls: cannot access AppendStream.php: No such file or directory ls: cannot access Stream.php: No such file or directory ls: cannot access CachingStream.php: No such file or directory ls: cannot access StreamDecoratorTrait.php: No such file or directory ls: cannot access GuzzleStreamWrapper.php: No such file or directory total 12 drwxrwxr-x 1 vagrant vagrant 4096 Aug 14 11:33 . drwxrwxr-x 1 vagrant vagrant 4096 Aug 14 11:33 .. ?????????? ? ? ? ? ?

在我重新启动机器（ vagrant reload ）后，文件变得可访问，因此我怀疑有安装/重新安装有问题。
这个问题已经出现在Linux mint 13主机以及Windows 7 64位主机上。 box是hashicorp/precise64
我想我已经找到了问题，这是由于重复安装 – 默认情况下，vagrant将主动主机目录/home/user/vagranthost到/vagrant 。 我所做的是，我添加了额外的子目录作为像/home/user/vagranthost/project挂载点到/vagrant/project ，从而创建一个冲突，流浪者不认识（还），让它挂载。
因此，解决方案是编辑Vagrantfile并更改行
config.vm.synced_folder "/home/ulkas/Develop/beauty/Beautyportal", "/vagrant/Beautyportal", owner: "vagrant", group: "vagrant", :mount_options => ['dmode=777', 'fmode=777']
成
config.vm.synced_folder "/home/ulkas/Develop/beauty", "/vagrant", owner: "vagrant", group: "vagrant", :mount_options => ['dmode=775', 'fmode=775']
为了调试，这是在mount命令的输出之前：
/vagrant on /vagrant type vboxsf (uid=1000,gid=1000,rw) /vagrant/Beautyportal on /vagrant/Beautyportal type vboxsf (uid=33,gid=1000,rw)
