I am trying to install the drivers for Velodyne 32E. I downloaded the folder from and then I am typing cmake ../ to build it.

I am getting an error:

--from catkin.environment_cache import generate_environment_script

--ImportError: No module named catkin.environment_cache

I have installed catkin_pkg using pip.

What should I do?

That is not the way to build any ROS package, including the Velodyne driver.

ROS packages are built using catkin_make, or some similar tool. See the catkin documentation, many tutorials and API documents are listed there.

EDIT: start with the first three catkin tutorials:

That should teach you how build this or any other ROS package.

EDIT2: There are instructions for installing ROS on OSX, but I have only used Linux. OSX does not look easy, but some people do successfully use it.

Those instructions recommend homebrew rather than macports.

Thank you for your reply! I am really new with all these. I haven't use ROS before. I though that by installing catkin and catkin_pkg, I would be okay. Apparently I am not. Could you please help me by enumerating a few steps that I have to follow? My goal is to convert pcap files to pcd files.

I forgot to mention that I am using a mac.

Thank you again! I did as you said and I found a problem installing pcl_ros: $catkin_make -DCMAKE_BUILD_TYPE=Release ... Add the installation prefix of "Eigen3" to CMAKE_PREFIX_PATH.....

I have Eigen3 installed with macports. What should I do?
