I am trying to install ROS on my MacBook Pro, with OS 10.8.3. The installation will not go beyond the installation of pydot. I first execute the command:

rosdep install --from-paths src --ignore-src --rosdistro groovy -y

Then, after moving through several other installations, the program asks for my password:

executing command [sudo pip install -U pydot]
Password:

After giving my password, the following output is given:

Downloading/unpacking pydot
  Running setup.py egg_info for package pydot
    Couldn't import dot_parser, loading of dot files will not be possible.

Thanks for any help.

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: *UPDATED

    1) sudo pip uninstall pyparsing
    2) sudo pip install https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz
    3) sudo pip install -U pydot pyparsing==1.5.7
try to rosmake, if will not go through repeat above steps and do set 4:
    4) 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.

Thanks for the advice. Unfortunately, it doesn't look like it's working. If I input the command

sudo pip install pyparsing==1.5.7

The output is:

Downloading/unpacking pyparsing==1.5.7
  Running setup.py egg_info for package pyparsing
    Traceback (most recent call last):

Not sure where the problem is. If I try to run rosdep install --from-paths src --ignore-src --rosdistro groovy -y, one of first errors I get is Couldn't import dot_parser, loading of dot files will not be possible.

So it seems that importing a dot parser is a problem, but I don't really know what that means or how to go about getting a solution.

Hmm strange. Did you uninstall pyparsing first? Can you try this pip install https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz

Can you show the output of "which python"?

Artem ( 2013-06-02 13:21:47 -0500 )edit

The output of "which python" is: /usr/bin/python.

I can't uninstall pyparsing. When I "sudo uninstall pyparsing" I get: Preparing Uninstall... Uninstall Began... Uninstall Failed... Reason: ErrorMissingBundle

When I "sudo pip uninstall pyparsing" I get: Cannot uninstall requirement pyparsing, not installed Storing complete log in /Users/jjameson/Library/Logs/pip.log

I successfully installed pyparsing with "sudo pip install https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz". I'm still unsure about how to remove the pyparsing code from the rosdep install.

You mean sudo pip uninstall pyparsing? Hmm strange.. actually I did not have this problem until I build python from homebrew. But you are using original python that comes by default.

Artem ( 2013-06-02 15:24:38 -0500 )edit

Ok so it looks as though this has been solved. First, I "sudo pip install https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz". Next, "sudo pip install -U pydot pyparsing==1..5.7". After, these two inputs, the system was ready to build the ROS dependencies. Thanks!
