export - Vagrant 错误: NFS is reporting that your exports file is invalid

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，出现错误:

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":

Can't open /etc/exports

我检查过，我没有 etc/exports 文件夹，因此我创建了一个并运行 vagrant reload。这让我:

我使用的是 Mac (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引发该错误的 Vagrant 源代码的存储库。

Answer 1

我在 VirtualBox 安装中安装了一些以前的图像/盒子，因此 /etc/exports 中已经存在一些无效条目。所以我必须清理该文件并重新启动我的 Vagrant 盒子。

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":

这是我在主机上所做的事情:

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

vagrant halt
vagrant up --provision
