Host OS: Mac OS 10.11.1
Guest OS: Ubuntu Trusty 64
Virtualbox: 4.3.30
Vagrant: 1.7.4
Example with trace thrown:
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ cat tt.py
import tempfile
with tempfile.TemporaryFile(dir="/vagrant") as tf:
tf.write("testing testing testing\n".encode('utf-8'))
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ python3.5 tt.py
Traceback (most recent call last):
File "tt.py", line 4, in <module>
with tempfile.TemporaryFile(dir="/vagrant") as tf:
File "/usr/lib/python3.5/tempfile.py", line 753, in TemporaryFile
newline=newline, encoding=encoding)
FileNotFoundError: [Errno 2] No such file or directory
I think the underlying system call that's causing the error (I attached the
full strace in case that's helpful):
open("/vagrant", O_RDWR|O_EXCL|O_DIRECTORY|O_NOFOLLOW|O_CLOEXEC|0x400000) = -1
EOPNOTSUPP (Operation not supported)
Finally, the mount point looks like this:
vagrant on /vagrant type vboxsf (uid=1000,gid=1000,rw)
