permission issues

[shadow-identity]

I have troubles with permissions.
Running blocks using sudo or under root:

$ sudo blocks 
Traceback (most recent call last):
  File "/bin/blocks", line 9, in <module>
    load_entry_point('blocks==0.1.4', 'console_scripts', 'blocks')()
  File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 519, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)

    return ep.load()
  File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2310, in load
    return self.resolve()

    module = __import__(self.module_name, fromlist=['__name__'], level=0)

    def __init__(self, *, device, **kwargs):
                        ^
SyntaxError: invalid syntax

running from user, blocks installed to system:

$ blocks

running from user, blocks installed to user directory (the one way to make blocks run, but I have permission issue here):

So how should I run it?
I'm on Fedora 22.
Thanks

happens because you invoke the program with pthon2, rebuild the application with python3 setup.py build && sudo python3 setup.py install (I opened #25 to prevent this in the future).
