[Pyparsing] Problems when installing version 2.0.0 using pip

[Álvaro Justen [Turicas]]

Hello,

I'm developing a project[https://github.com/NAMD/pypelinin] that uses
python-graph-dot[https://pypi.python.org/pypi/python-graph-dot], which
depends on pyparsing.
I figured out that you released version 2.0.0 some hours ago because I
tried to package my library to test some stuff and the installation
process failed by a SyntaxError when pip was trying to install
pyparsing.

I'm using Python 2.7.3 and all the log can be found at:
https://gist.github.com/turicas/5046284

Basically, the SyntaxError exception is raised on file "pyparsing.py",
line 629 ("nonlocal limit,foundArity").
To reproduce this problem you just need to install it in a new virtualenv:

cd /tmp
virtualenv pyparsing-test
source pyparsing-test/bin/activate
pip install python-graph-dot
deactivate
rm -rf pyparsing-test

Is there any plans on fixing this problem? I'm considering removing
python-graph-dot dependency in my library for now because I simply
can't install it because of this bug.

Thanks,
[]s

pip install pyparsing==1.5.7

Yes, I know I can do it, but sincerely I don't want to since my library
does not depends directly on pyparsing.

Hopefully this will explicitly load the Python2-compatible version of

pyparsing, and then pydot won't need to try to autoresolve it.

*Seriously* that you will break everything that needs pyparsing and uses
Python 2?

Can you precede your install of pydot with:

pip install pyparsing=3D=3D1.5.7

Hopefully this will explicitly load the Python2-compatible version of =
pyparsing, and then pydot won't need to try to autoresolve it.

Alvaro -

Unfortunately this is the best I can offer. We are in the awkward in-betwee=
n Python2-or-Python3 compatibility period, which is likely to last a few mo=
re years at least. My previous approach to handling the version dichotomy w=
as error-prone, and I finally decided to just move forward to Python 3 as m=
y main supported Python version. Starting with 2.0.1, I will start converti=
ng over the supporting code and examples to be more Python3 idiomatic - thi=
s of course will not affect the 1.5.x branch of pyparsing. Fortunately both=
pip and easy_install offer a command syntax to explicitly request a partic=
ular version of pyparsing, so Python 2 users do have a not-too-terrible wor=
karound for the default behavior of installing the latest version of a pack=
age.
