Disclaimer: This is a temporary workaround which worked for me, not a permanent fix and may not work for everyone
Many of us have already tried to enjoy the flavor of new OS by Apple, macOS High Sierra. And doing that might have given you nightmares, if you were using vagrant based project.
If anyone is facing missing files or file changes not getting detected issue inside Vagrant, this might be because of compatibility issues with Apple’s latest APFS (apple file system) and Vagrant’s synced folder type: nfs.
I experienced this a couple of weeks ago, when I upgraded to beta version of masOS High Sierra. I was not able to see few modules (like views, taxonomy) and files present inside vagrant (guest) even though these were actually present in my mac machine (host). This is an already reported issue.
After struggling for next few days and nights, I found the quickest possible solution for this problem which worked for me.
Please follow the steps mentioned below:
Add the following part only:
Add this code in Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| function of your VagrantFile. You can also refer to VagrantFile line number: 108 & 114 given in https://github.com/navneet0693/high-sierra-vagrant-problem.
