subprocess.run was added in Python 3.5, per https://docs.python.org/3/library/subprocess.html#subprocess.run

Use the old Popen instead?

Do we want to support Python 3 versions older than 3.5? I say no because:

 - Even Debian's “oldstable” has 3.5
 - 3.5 is considered one of the first Python 3 versions which are
   actually really usable (all is rosy with 3.6 or newer).
 - Support for 3.5 will end on 2020-09-13

Instead, I would figure out the issue with Pylint and keep using
“subprocess.run()”.

The issue would not be with Python3 itself, but with Python2. Don't we still need to support both versions in webkitpy?

(subprocess.run is not available in python2: https://docs.python.org/2/library/subprocess.html )

[Philippe Normand]

Right, webkitpy is not yet fully ported to Python3.
