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":

Since I cloned my old Macbook into my brand new Macbook Pro machine where I had some previous boxes installed in my VirtualBox installation, I ended up having few invalid entries in /etc/exports. You will need to clean up that file and restart Vagrant box.

SOLUTION. You’ll need to run following command to fix it:

sudo rm /etc/exports
sudo touch /etc/exports
vagrant halt
vagrant up --provision

You’re all set. Happy hacking!
