path import issue

[dgutman]

I am getting an error related to specifying a path.

TypeError: argument should be string, bytes or integer, not PosixPath

This was with the pip install niwidgets basic installation; I had trouble with this on 2.7.2 so I switched my kernel to 3.5.3 and am still having the same issue...

This should be fixed since commit 4b19e05 (and in the latest version on pypi), but let me know if you have any more problems.
