rosdep keys cannot be resolved to system dependencies

Those packages are definitely part of rosdep/osx/homebrew:

https://github.com/ros/rosdistro/blob/b8242094ec43dfa7c146e22496e60ed18f97be71/rosdep/osx-homebrew.yaml#L461
https://github.com/ros/rosdistro/blob/b8242094ec43dfa7c146e22496e60ed18f97be71/rosdep/osx-homebrew.yaml#L94
https://github.com/ros/rosdistro/blob/b8242094ec43dfa7c146e22496e60ed18f97be71/rosdep/osx-homebrew.yaml#L178

Maybe you got a bad rosdep clone or something? Consider:

sudo rm -rf /etc/ros/rosdep
sudo rosdep init
rosdep update

And then try the rosdep line again:

rosdep install --from-paths src --ignore-src --rosdistro ${ROS_DISTRO} -y --as-root pip:no --skip-keys="gazebo"

If it works correctly, create the install dir and run the build manually to avoid re-downloading everything:

ros-install-osx/install

Line 150 in 6472e86

# Clean out or create the install directory.

That was it. I had a non-empty /etc/ros/rosdep directory from a failed installation attempt some months ago. The rest of the installation process was successful after this fix.

Thanks for the feedback! I guess this one can be closed now.

I'm having a similar problem but i'm not sure how to solve it!
I'm trying to install VLP16 to my ubuntu 16 with ROS kinetic but I also have Lego Loam installed and when i try the following, I get the error message!

~/catkin_ws$ rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
lego_loam: Cannot locate rosdep definition for [gtsam]
