from packaging import version as pack_version ImportError: No module named packaging

[David Gabriel]

Dears,

When I run this command I got this error message:

ubuntu at orchestrateur:/tmp/pack$ virtualenv -p $(which python3.5) .
Running virtualenv with interpreter /usr/local/sbin/.
Traceback (most recent call last):
  File "/usr/bin/virtualenv", line 3, in <module>
    virtualenv.main()
  File "/usr/lib/python2.7/dist-packages/virtualenv.py", line 784, in main
    popen = subprocess.Popen([interpreter, file] + sys.argv[1:], env=env)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 13] Permission denied


This error is also reproducible using sudo.
Please advise how to fix it.

Thanks in advance.
Best regards
