Pynder Import Error (AttributeError: 'module' object has no attribute 'api')

[SHABINTHEGREAT]

Pynder gives this Error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/pynder/__init__.py", line 1, in <module>
    from pynder.session import Session  # NOQA
  File "/Library/Python/2.7/site-packages/pynder/session.py", line 4, in <module>
    import pynder.api as api
AttributeError: 'module' object has no attribute 'api'

How to fix/resolve it?

Thank you!
