Question

我正在尝试使用这些instructions设置Discourse开发环境。但是，当我运行Vagrant时，我收到错误：

NFS报告您的导出文件无效。 Vagrant呢   在对文件进行任何更改之前进行此检查。请改正   以下问题并执行＆＃34; vagrant reload＆＃34;：

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/框，因此/etc/exports中已经存在一些无效条目。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 2

我在OS X 10.9 Mavericks（13A603）上使用Vagrant 1.4.1和VirtualBox 4.3.6遇到了这个问题。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，这在下面的评论中指出。

$ sudo touch /etc/exports

然后我能够成功运行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

然后快速vagrant reload我就开始运行了！

Answer 3

对我来说，这个错误开始出现在工作的Vagrant环境中。

我已经重命名了Vagrant正在运行的目录。为了解决它，我跑了＆sudo vi / etc / exports＆＃39;并修复了路径名，使其指向我当前的目录。

Answer 4

同样的事发生在我身上。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
"/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 流浪汉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）：

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
删除/ etc / exports

sudo mv /etc/exports ~/Desktop/exports
重写/ etc / exports

vagrant up
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：

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Spinner
        android:id="@+id/spinner"
        android:background="#fff"
        android:layout_marginRight="12dp"
        android:layout_marginLeft="12dp"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        android:layout_width="match_parent"
        android:layout_height="45dp"/>

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/spinner"
        android:scrollbars="none"
        android:overScrollMode="never"
        tools:adjustViewBounds="true"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginRight="12dp"
        android:layout_marginLeft="12dp"
        android:fillViewport="true">

    <ImageView
        android:id="@+id/image"
        android:src="@drawable/basic_01"
        android:scaleType="fitStart"
        android:focusableInTouchMode="true"
        android:layout_below="@+id/spinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    </ScrollView>

</RelativeLayout>

<android.support.design.widget.NavigationView
    app:headerLayout="@layout/header"
    android:layout_width="350dp"
    android:layout_height="match_parent"
    app:menu="@menu/nav_header"
    android:id="@+id/navigation_view"
    android:layout_gravity="start">

</android.support.design.widget.NavigationView>

如果不确定是否会覆盖项目的当前状态，请不要使用“无用的--provision”。

Answer 7

在Ubuntu 12主机/ Ubuntu 12上，以下Discourse为我工作：

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：我还必须将由Vagrant确定的主机IP地址和Vagrant确定的访客IP地址添加到防火墙例外。

Answer 8

我跑了vagrant box list，这告诉我有4个无用的盒子（一定时候偶然创建了它们-我通常只用一个。）然后我跑了vagrant box prune，它删除了我未使用的盒子。然后vagrant up重新开始工作！

Answer 9

尝试使用 Discourse as Your First Rails App 中提到的已知良好版本的VirtualBox和Vagrant：

Vagrant 1.1.2
VirtualBox 4.2.10

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