我相信这里使用的开发环境非常普遍。我检查了nfsd，如下所示：
ps aux | grep nfsd
输出显示nfsd正在运行。
但是，使用vagrant up命令，我收到以下错误消息。VM 管理器还显示一些错误消息。该vagrant reload命令也无济于事。

The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in
the 'poweroff' state. Please verify everything is configured
properly and try again.
If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since
the GUI often has more helpful error messages than Vagrant can
retrieve. For example, if you're using VirtualBox, run
`vagrant up` while the VirtualBox GUI is open.
The primary issue for this error is that the provider you're
using is not properly configured. This is very rarely a Vagrant
issue.
如果您能指导我在哪里调查，我将不胜感激。祝福
