Can't run SITL: JSON error

Hello,

I am trying to get the dronekit-sitl up and running and am running into errors. I've tried installing from pip: pip install dronekit-sitl and from the github master: pip install git+https://github.com/dronekit/dronekit-sitl

but when I install from github master and try running dronekit-sitl --list I get the error:


~$ dronekit-sitl --list
Traceback (most recent call last):
  File "/usr/local/bin/dronekit-sitl", line 9, in <module>
    load_entry_point('dronekit-sitl==3.0.1', 'console_scripts', 'dronekit-sitl')()
  File "/usr/local/lib/python2.7/dist-packages/dronekit_sitl/__init__.py", line 349, in main
    versions = version_list()
  File "/usr/local/lib/python2.7/dist-packages/dronekit_sitl/__init__.py", line 88, in version_list
    versions = json.loads(raw)
  File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

and when I try and run dronekit-sitl copter-3.3.0 --home=-35.363261, 149.165230, 584, 353 I get the error:

~$ dronekit-sitl copter-3.3.0 --home=-35.363261, 149.165230, 584, 353

    raise IOError, ('http error', errcode, errmsg, headers)
IOError: ('http error', 302, 'Moved Temporarily', <httplib.HTTPMessage instance at 0x7f3a0fab25a8>)

Note: I am behind a proxy which could possibly be why I'm getting the http error?

Any help would be appreciated
