我知道有很多关于这方面的问题，但是请花时间研究一下，它与其他人不一样。
我正在使用Vagrant 1.9.4和虚拟框5.1.18。当我做了流浪汉，它被困在Mounting NFS共享文件夹..我做了vagrant调试并有这个日志消息

Vagrant assumes that this means the command failed!
mount -o vers=3,udp 10.20.48.1:/var/www/vhosts/clearcare /var/www/html/clearcare/current
Stdout from the command:
Stderr from the command:
