MicroPy  Failed to Create Stub Links!
MicroPy  OSError: [Errno 38] Function not implemented: '/home/lemariva/.micropy/stubs/BradenM-micropy-stubs-27ee48a' -> '/home/lemariva/Documents/work/lemariva.com/Github/MicroPy/.micropy/BradenM-micropy-stubs-27ee48a'
lemariva@l:~/Documents/work/lemariva.com/Github/MicroPy$

The problem appears on Ubuntu (20.04 LTS).
An exFAT partition is mounted on '/home/lemariva/Documents/work/' (encrypted and shared with Windows 10 - that's why exFAT). The exFAT file system does not support soft/hard links. The line:

source.symlink_to(target, target_is_directory=True)

generates the exception.

Possible Solution
If the error occurs (errno 38), copy the folders instead of making a link.
