Hi guys,
I'm running into an error when installing ROS (melodic) on Ubuntu (18.04). As I have absolutely no experience with UNIX, I don't really know what's going on or how to fix it.
I'm following these instructions:
[melodic installation from source](http://wiki.ros.org/melodic/Installation/Source "Installing from source")
Everything worked up to point *2.1.1 Resolving Dependencies*. Doing this step (again), I get the info:
~/ros_catkin_ws$ rosdep install --from-paths src --ignore-src --rosdistro melodic -y
executing command [sudo -H apt-get install -y python-rosdep]
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'python-rosdep2' instead of 'python-rosdep'
python-rosdep2 is already the newest version (0.11.8-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
ERROR: the following rosdeps failed to install
apt: Failed to detect successful installation of [python-rosdep]
Then I proceed with the installation tutorial trying to build the catkin workspace:
~/ros_catkin_ws$ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release
Traceback (most recent call last):
File "./src/catkin/bin/catkin_make_isolated", line 12, in
from catkin.builder import build_workspace_isolated
File "./src/catkin/bin/../python/catkin/builder.py", line 66, in
from catkin_pkg.terminal_color import ansi, disable_ANSI_colors, fmt, sanitize
ImportError: No module named terminal_color
This is my Ubuntu release:
~/ros_catkin_ws$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
If you need any additional info, please ask and tell me how to get them.
While searching for my issue, I came accross [this ROS Answer](https://answers.ros.org/question/294146/importerror-when-running-catkin_make_isolated/ "ImportError when running catkin_make_isolated"), but I don't see how this should help me fix the problem.
Thanks,
André
