Re: [Pyparsing] Problems when installing version 2.0.0 using pip

[Paul M. <pt...@au...>]

Can you precede your install of pydot with:

    pip install pyparsing==1.5.7

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

Subject: [Pyparsing] Problems when installing version 2.0.0 using pip

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
