TypeError when initializing Nco object using python/pynco

I am new to using using NCO tools and their Python bindings for working with netCDF files. I have successfully installed the NCO tools and the pynco package (using pip) following the instructions here. But I am getting an error when I try to initialize an object.

Here are the commands I'm using:

from nco import Nco

nco = Nco()

And the error is:

Traceback (most recent call last):

  File "<input>", line 1, in <module>

  File "C:Python27ArcGIS10.5libsite-packagesnconco.py", line 54, in __init__

    self.NCOpath = os.path.split(which('ncks'))[0]

  File "C:Python27ArcGIS10.5libntpath.py", line 180, in split

    d, p = splitdrive(p)

  File "C:Python27ArcGIS10.5libntpath.py", line 115, in splitdrive

    if len(p) > 1:

TypeError: object of type 'NoneType' has no len()

This suggests to me that the install may not have worked properly, though I can run NCO commands from the command line.

Any idea what the problem may be?

The fork of pynco you link is 2 years old. I'd try the original at github.com/nco/pynco and as they suggest use the Conda install.
