I would like to use rviz in groovy at Mac OS X (mountain lion). I builded rviz with homebrew described in

rviz doesn't work well. Using python installed by homebrew would cause this problem. If I remove python by brew, rviz works well. But other ros system does't work. Which python should I use. (installed by brew or originally installed)

Error messages were listed below.

I removed python installed by homebrew. And, I removed also installed python libraries in /usr/local/lib/python2.7/site-packages and /usr/local/share/python. After that, I retried install sequence. Then, rviz seemed to work well.

Looks like something is wrong with rosdep, make sure you have the latest version:

sudo pip install -U rosdep

rosdep is updated. From this site , same problem occured in other program. It caused python installed by brew.

looks like this might be a problem installing Python from homebrew, that ticket you linked seems like the right direction for debugging this.

William, which python do you use ? Originally installed or installed by homebrew.

I always use the Python that ships from Apple (2.7)
