BUG: AttributeError: module 'docutils.nodes' has no attribute 'reprunicode'

[antoinecollet5]

It seems that this line causes an error https://github.com/vidartf/nbsphinx-link/blob/f1682a8b5bfd884bfed7ef7dfaf0810c6ae8a543/nbsphinx_link/__init__.py#L192

because docutils removed reprunicode in v0.21.

I do not known if nbsphinx-link supports python 2? If so, it can probably be solved using something like:

# Note: reprunicode is a compatibility hack for python 2. It has been removed 
# from docutils in v0.21.
is_py2 = int(platform.python_version()) == 2
if is_py2:
    path = nodes.reprunicode(path)

and

target_root = env.config.nbsphinx_link_target_root
target = utils.relative_path(target_root, abs_path)
if is_py2:
    target = nodes.reprunicode(target)
target = target.replace(os.path.sep, '/')
env.metadata[env.docname]['nbsphinx-link-target'] = target

If you agree, I open a PR.

New release (1.3.1) should be out with the contributed fix. Please ping me if there are any issues with it.

@vidartf 1.3.1 seems to solve the issue :)
