Vagrant错误:NFS报告您的导出文件无效

Question

我正在尝试使用这些说明设置Discourse开发环境.但是,当我运行Vagrant时,我得到错误:

NFS报告您的导出文件无效.在对文件进行任何更改之前,Vagrant会进行此检查.请更正以下问题并执行"vagrant reload":

无法打开/ etc/exports

我查了一下,而且我没有etc/exports文件夹,所以我创建了一个并运行了vagrant reload.这让我:

我在Mac上(OS X 10.6.8).我该如何解决？我尝试搜索原始错误消息,我发现的只是一些包含抛出它的Vagrant源代码的存储库.

Answer 1

我的VirtualBox安装中安装了一些以前的图像/盒子,所以已经有一些无效的条目/etc/exports了.所以我必须清理该文件并重新启动我的Vagrant框.

NFS is reporting that your exports file is invalid. Vagrant does
this check before making any changes to the file. Please correct
the issues below and execute "vagrant reload":

这是我在主机上做的事情:

sudo rm /etc/exports
sudo touch /etc/exports

vagrant halt
vagrant up --provision

Answer 2

我在OS X 10.9 Mavericks(13A603)上遇到了Vagrant 1.4.1和VirtualBox 4.3.6这个问题.我能够通过一个简单的命令来修复它,以创建缺少的/ etc/exports文件.在OS X上运行,而不是guest,如下面的评论所述.

$ sudo touch /etc/exports

然后我才能成功运行vagrant up.我确实遇到了另一个错误,其中Guest Additions不是最新的,但我通过安装vagrant-vbguest插件修复了这个问题.

$ vagrant plugin install vagrant-vbguest

然后一个快速的vagrant reload我开始运行!

Answer 3

对我来说,这个错误开始出现在一个有效的Vagrant环境中.

我已经重命名了Vagrant运行的目录.为了修复它,我运行'sudo vi/etc/exports'并修复了路径名,使其指向我当前的目录.

Answer 4

这样的事情我也经历过.我从另一个项目复制了我的Vagrantfile,忘了更改NFS设置.这导致当前VM挂载我复制原始Vagrantfile的VM的父文件夹.所以我这样做了:

vagrant halt
vagrant up

仍然有同样的错误.所以我跟踪了位于/ etc/exports的导出文件,如下所示:

# VAGRANT-BEGIN: 501 64e10d4d-342e-4f55-b69a-97edda35742f
"/Users/[username]/vagrant" 192.168.11.12 -alldirs -mapall=501:20
# VAGRANT-END: 501 64e10d4d-342e-4f55-b69a-97edda35742f
# VAGRANT-BEGIN: 501 b3c6e7fe-95d4-48db-8876-c89d3e07af8d

# VAGRANT-END: 501 b3c6e7fe-95d4-48db-8876-c89d3e07af8d
# VAGRANT-BEGIN: 501 3e2aabfd-ce63-441b-85a2-1b51e8beb863
"/Users/[username]/Sites/app" 192.168.11.125 -alldirs -mapall=501:20
# VAGRANT-END: 501 3e2aabfd-ce63-441b-85a2-1b51e8beb863
# VAGRANT-BEGIN: 501 ff92e353-9f6d-48ee-9d76-e29b33f1dd60

# VAGRANT-END: 501 ff92e353-9f6d-48ee-9d76-e29b33f1dd60

最后两条路径是相同的.所以我删除了最后三行并运行:

vagrant halt && vagrant up

现在一切似乎都运转正常.

OSX 10.11.1 Vagrant 1.7.4

Answer 5

我不想经历降级的麻烦.这就是我所做的(仍然需要一段时间,但比降级恕我直言的麻烦更少):

1. 在VM Vagrantfile中,对于任何已同步的文件夹,禁用NFS

   config.vm.synced_folder ".", "/vagrant", nfs: false

2. 删除了/ etc/exports

   sudo mv /etc/exports ~/Desktop/exports

3. 重写/ etc/exports

   vagrant up

4. 如果您希望/需要在VM上启用NFS,请重新启用NFS

   config.vm.synced_folder ".", "/vagrant", nfs: true

Answer 6

只需运行以下命令：

sudo rm /etc/exports
sudo touch /etc/exports
vagrant reload

请不要使用vagrant up --provision，如果你不知道，这将您的项目不覆盖当前状态。

Answer 7

尝试使用 Discourse 中提到的 VirtualBox 和 Vagrant 的已知良好版本作为您的第一个 Rails 应用程序：

• 流浪者1.1.2
• 虚拟盒4.2.10

我在 Mac (OS X 10.9 (Mavericks)) 上遇到了同样的问题，但回滚到这些版本似乎解决了我的问题。
