stream浪汉错误：NFS报告您的导出文件无效

我正在尝试使用这些指令来build立话语开发环境。 但是，当我运行stream浪汉，我得到的错误：

NFS正在报告您的导出文件无效。 Vagrant会在对文件进行任何更改之前进行检查。 请更正以下问题并执行“stream浪者重新加载”：

无法打开/ etc / exports

我检查了，我没有一个etc / exports文件夹，所以我创build了一个并运行vagrant reload 。 这让我：

我在Mac（OS X 10.6.8）上。 我该如何解决？ 我试图寻找原始的错误消息，而我发现的只是一些包含引发它的Vagrant源代码的存储库。

Answer 1

尝试使用已知好的版本的VirtualBox和Vagrant在Discourse中logging为您的第一次Rails应用程序 ：

• stream浪者 1.1.2
• VirtualBox 4.2.10

我在Mac（OS X 10.9（Mavericks））上遇到了同样的问题，但是回滚到这些版本似乎为我解决了这个问题。

Answer 2

我有一些以前的图像/盒安装在我的VirtualBox安装，所以已经在/etc/exports中有一些无效的条目。 所以我不得不清理那个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 3

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。 我能够用一个简单的命令来修复它，以创build缺less的/ etc / exports文件。 在OS X上运行这个，而不是在下面的注释中指出的客人。

 $ sudo touch /etc/exports 

那时我才能够成功地逃跑vagrant up 。 我遇到了Guest Additions不是最新的另一个错误，但我通过安装vagrant-vbguest插件来解决这个问题。

 $ vagrant plugin install vagrant-vbguest 

然后一个快速的vagrant reload ，我起身运行！

Answer 4

对我来说，这个错误开始出现在一个工作的stream浪者环境。

我已经重命名Vagrant运行的目录。 为了解决这个问题，我运行了“sudo vi / etc / exports”，并修复了path名，使其指向我的当前目录。

Answer 5

我不想经历降级的麻烦。 这就是我所做的（仍然花了一段时间，但比降级IMHO更less麻烦）：

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/需要在您的VM上启用NFS，请重新启用NFS

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

Answer 6

这样的事情我也经历过。 我从另一个项目中复制了我的Vagrant文​​件，并忘记更改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。 所以我追踪了位于/ etc / exports的出口文件，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 "/Users/[username]/Sites/molitech-oms" 192.168.11.124 -alldirs -mapall=501:20 # 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 "/Users/[username]/Sites" 192.168.11.126 -alldirs -mapall=501:20 # VAGRANT-END: 501 ff92e353-9f6d-48ee-9d76-e29b33f1dd60 

最后两条path是相同的。 所以我删除了最后三行，跑了：

 vagrant halt && vagrant up 

现在一切似乎都工作正常。

OSX 10.11.1stream浪者1.7.4

Answer 7

在Ubuntu 12主机/ Ubuntu 12的客人下面为Discourse工作 ：

 nfs_setting = RUBY_PLATFORM =~ /darwin/ || RUBY_PLATFORM =~ /linux/ config.vm.synced_folder ".", "/vagrant", id: "vagrant-root", type: "nfs", nfs_udp: "true", nfs_version: "4", :nfs => nfs_setting 

注意：我还必须添加由Vagrant确定的主机IP地址和由Vagrant确定的访客IP地址，以防止防火墙exception。
