I have this error as well:

Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/tornado/web.py", line 1445, in _execute
    result = yield result

    value = future.result()

TypeError: get() missing 1 required positional argument: 'path'

What was your resolution?

A StaticFileHandler must be bound with a pattern as shown in the docs: the (.*) is necessary to tell the StaticFileHandler what part of the path is the filename.
