NotImplementedError: No usable implementation found! whith usable implementations on the system.

[AlbericC]

platform in linux mint17.1 mate (ubuntu-based) with an almost fresh install.

import plyer
plyer.notification
plyer.notification.notify()

raises NotImplementedError: No usable implementation found! with this traceback.

----> 1 plyer.notification.notify()
/usr/local/lib/python3.4/dist-packages/plyer/facades.py in notify(self, title, message, app_name, app_icon, timeout)
     96         '''
     97         self._notify(title=title, message=message, app_icon=app_icon,

--> 103         raise NotImplementedError("No usable implementation found!")

trying to corner the malfunction and to determine whetther my setup is wrong, I tried this :

Python 3.4.0 (default, Apr 11 2014, 13:05:11) 
[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import plyer
>>> plyer.utils.platform
'unknown'
>>> plyer.utils._determine_platform()
'unknown'
>>> plyer.utils._sys_platform
'linux'
>>> plyer.utils._sys_platform.startswith("linux")   # mimics test on utils.py L38
True

so according to utils.py, plyer.utils.platform should be 'linux' ... but apparently _determine_platform() does not return what seems straightforward.

it can be worked around for testing purposes with

from sys import platform
if platform == 'linux':
    plyer.utils.platform = 'linux'  # only for testing purposes !!! 

but for obvious reasons, this is does not look like a good idea.

this isse is resolved by installing the master branch from github, but is (today) apparent in the pypi version.
