[New-bugs-announce] [issue28552] Distutils fail if sys.executable is None

[Alexander P]

New submission from Alexander P:

For example, Jython 2.7. When we try to execute `jython-standalone -m pip`, distutils.sysconfig tries to parse sys.executable as a path and obviously fails:

    Traceback (most recent call last):
      File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/runpy.py", line 161, in _run_module_as_main
