"No module named catkin_pkg.package" on catkin_make w/ Indigo

I have the problem after anaconda is installed.

Solution 1: turn off anaconda

In the end of file ~/.bashrc, you will find export PATH="/home/YOURUSRNAME/anaconda3/bin:$PATH" .

In fact the ROS should use python in /opt/ros/indigo/lib/python2.7/dist-packages. Uncomment it and source ~/.bashrc then it works.

Solution 2:

Without turning off anaconda, just run pip install catkin_pkg, it may be helpful.

Change python version system-wide

To change python version system-wide we can use update-alternatives command. Logged in as a root user, first list all available python alternatives:

# update-alternatives --list python
update-alternatives: error: no alternatives for python

The above error message means that no python alternatives has been recognized by update-alternatives command. For this reason we need to update our alternatives table and include both python2.7 and python3.4:

# update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
update-alternatives: using /usr/bin/python2.7 to provide /usr/bin/python (python) in auto mode
# update-alternatives --install /usr/bin/python python /usr/bin/python3.4 2
update-alternatives: using /usr/bin/python3.4 to provide /usr/bin/python (python) in auto mode
