The automated build does not work. The py35 build fails with the following (ex. job 267816857):

AttributeError: '_NamespacePath' object has no attribute 'sort'

I suspect that this problem is not really with the current source of this extension, but rather an issue with pip and/or the tox configuration being used. Using a more recent version pip and setuptools shows that the tox build works; however, I can't seem to get it to work with Travis CI (I haven't had that much experience with using it).

I believe the following bug covers of the reason why, but I'm not 100% sure how to apply the workaround changes for the current automated build process:

pypa/pip - '_NamespacePath' object has no attribute 'sort'
pypa/pip#4216

I was hoping a pip v9.0.2 update would fix this, but I'm not sure when an update will ever be released.

tox: force pip upgrade
3a694eb 
The Travis CI environment prepares a test environment with the most
recent version of pip available (v9.0.1); however, using this
version results in the following error [1]:

    AttributeError: '_NamespacePath' object has no attribute 'sort'

Adjusting the tox requirements to forcefully update pip to the
newest version for the interim. When pip v9.0.2+ is available, this
commit can be reverted.

[1]: #45

This issue has been addressed on master to allow Travis CI to be functional again.

For user's experiencing the same issue in their environment, it is recommended to update their setuptools package (python -m pip install --upgrade setuptools).

tox: remove forced pip installation

The most recent version of Travis CI's Python build [1] appears to no
longer require a force update of the pip command line [2]. Tested with
image 'travisci/ci-garnet:packer-1512502276-986baf0'.

tox: remove explicit custom python path
e88ef73 
Removes the custom Python path explicitly set in the tox configuration
file. This should resolve situations [1] where pip may not install
required packages (and dependencies) into target virtualenv since they
are already provided in PYTHONPATH (see also [2]).

Thank you YB_Park, that helped me so much. I have no idea though why that issue came up today, even though yesterday it worked just fine!

Thanks YB_Park. That line fix really should be incorportated into the next master build.

suggest line 2121 be changed to:

try:
orig_path=sorted(orig_path,key=position_in_sys_path)
except AttributeError:
print("BUG: Is it bad if orig_path is not sorted correctly?")
