After hours of unsuccessfully trying to use objectpath in a Python3-script, I made the following simple experiment:

>>> from objectpath import *

>>> tree=Tree({"a":1})

>>> tree.execute("$.a")

Expected output: 1

Success with python (2)

~$ python

>>> from objectpath import *

>>> tree=Tree({"a":1})

>>> tree.execute("$.a")

Error with python3:

Is there something wrong with my installation of Python3 ?
objectpath in P3 neither works in scripts nor on console

During handling of the above exception, another exception occurred:

To run this in Python 3.x you should pip3 install objectpath otherwise it won't work.

See below how I ran your code:
