有时无法访问同步文件夹中新创建的文件[关闭]答案

【问题描述】：

有时我得到了新创建的文件，但我无法访问，尽管我可以在控制台中列出它们。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']

当我在主机和来宾中创建/修改文件时会发生这种情况，它们只是变得无法访问：

cannot access GuzzleStreamWrapper.php: No such file or directory

我可以在控制台中列出它们，但没有权限（看起来像挂载问题）：

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

重启机器后（vagrant reload），文件就可以访问了，因此我怀疑挂载/重新挂载有问题。

这个问题出现在 linux mint 13 主机和 windows 7 64 位主机上。盒子是hashicorp/precise64

【解决方案1】：

我想我找到了问题，这是由于重复安装 - 默认情况下，vagrant 将活动主机目录 /home/user/vagranthost 安装到 /vagrant 中。我所做的是，我添加了额外的子目录作为像 /home/user/vagranthost/project 这样的挂载点到 /vagrant/project 中，从而产生了一个冲突，它 vagrant 还不能识别并让它挂载。

因此，解决此问题的方法是编辑 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']

进入

config.vm.synced_folder "/home/ulkas/Develop/beauty", "/vagrant", owner: "vagrant", group: "vagrant", :mount_options => ['dmode=775', 'fmode=775']

为了调试，这是之前mount命令的输出：

/vagrant on /vagrant type vboxsf (uid=1000,gid=1000,rw)
/vagrant/Beautyportal on /vagrant/Beautyportal type vboxsf (uid=33,gid=1000,rw)
