Support for older versions of Python

[federico-tesser]

con Python 3.6, la “subprocess.Popen” non prende come parametro “text”, che è stato inserito dalla versione 3.7, bensì “universal_newlines”.

Thanks @federico-tesser!

Using a virtualenv with a newer version of Python might be a solution?

Hi @fbeneventi, thanks to you! :-)

That could be a solution, together with the fact of
explicitly saying what version of Python is required.

Otherwise, what about a check related to the minor of
the version? Something like

if (sys.version_info.minor > 6) then...
else ...
