Revision history [back]

I've just had this problem. The problem is in the version on pyparsing which is 2.0.0 and was designed for python 3.0. To resolve the problem you have to downgrade the pyparsing module. If you actually run this line, it will build pydot. sudo pip install -U pydot pyparsing==1.5.7 But I don't know how to pass the parameter "pyparsing==1.5.7" to rosdep. Next time you run rosdep install it will fetch again the same 2.0 version of pyparsing.

This is what I did:

1) sudo pip uninstall pyparsing
2) sudo pip install pyparsing==1.5.7
3) remove this line "pyparsing" from /Library/Python/2.7/site-packages/pydot-1.0.28-py2.7.egg-info/requires.txt or where you store site-packages.
