Can not get pythonect running on Ubuntu. AttributeError

[owigger]

Hello, I am a newbie both to pythonect and python. I am just trying to get pythonect up and running on plain Ubuntu 18.04, never used python before.

Whatever I do, pythonect crashes horribly with lots of gibberish, Traceback, and the inevitable

           AttributeError: can't set attribute

error. For example:

$ which pythonect
~/.local/bin/pythonect

$ pythonect
Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)
[Pythonect 0.6.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 1+1

Traceback (most recent call last):
File "~/.local/lib/python2.7/site-packages/Pythonect-0.6.0-py2.7.egg/pythonect/internal/eval.py", line 792, in eval
graph = parse(source)

self.node = _ordereddict.OrderedDict() # dictionary for node attributes
AttributeError: can't set attribute

I tried installing pythonect with pip, easy_install, or git clone. The result is always the same. I run the nose test in the git checkout:

pythonect$ python setup.py install --user
...
Finished processing dependencies for Pythonect==0.6.0

pythonect$ python setup.py nosetests
1 test_command_mode (test_interpreter.TestPythonectInterpreter) ... ERROR

ERROR: test_command_mode (test_interpreter.TestPythonectInterpreter)
Traceback (most recent call last):

File "~/pythonect/pythonect/internal/_graph.py", line 47, in init
self.node = _ordereddict.OrderedDict() # dictionary for node attributes

Please, I am just following the tutorials. What am I doing wrong??

Hoi @owigger! I was able to reproduce as well:

virtualenv --python $(which python2) virtualenv
. virtualenv/bin/activate
pip install pythonect
pythonect

The metadata says it's Python 2.7 compatible, but the last release was six years ago, so I suspect it's incompatible with recent Python 2.7 versions.
