Hello RoboUsers!

I would like to use the subprocess python module in Robofont.
If I launch the following script from sublime/terminal:
import subprocess
subprocess.call([‘vfb2ufo’, ‘font.ufo’])

this is the output that I receive:
VFB2UFO Converter
Copyright (c) 2013-2015 by Fontlab Ltd.
Build 2015-01-23

Otherwise, launching the same file from Robofont, I receive this output:
Traceback (most recent call last):
File “test_subprocess.py”, line 2, in <module>
File “subprocess.pyc”, line 524, in call
File “subprocess.pyc”, line 711, in __init__
File “subprocess.pyc”, line 1308, in _execute_child
OSError: [Errno 2] No such file or directory

There seems to be a problem related to paths, but using something like:
os.path.join(os.getcwd(), ‘font.ufo’)
doesn’t fix the problem.

Any tips?
Actually I’d like to use the vfb2ufo tool someway, so if there’s an alternative to subprocess module is of course welcome.

Thanks
