Description

Was attempting to create and build an addon.
I expected it to generate the add-on without error.
The add-on is successfully created but there is an error:

  File "/usr/lib/python2.7/subprocess.py", line 394, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1047, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

What I Did

I ran plonecli create addon
The output is shown below.

plonecli create addon myplone.example2

RUN: mrbob bobtemplates.plone:addon -O myplone.example2

Start with the post_render path in bobtemplates/plone/addon.py and the run_isort call in bobtemplates/plone/utils.py. Reproduce plonecli create addon myplone.example2 and inspect which subprocess executable is missing when run_isort runs. Done means addon creation completes without the OSError.
