Invoking "make -j4 -l4" failed, ImportError: No module named 'em'
Hi all,
After installing some rqt related packages, when running "catkin_make" I get:
make: *** [all] Error 2
Invoking "make -j4 -l4" failed
Examining the output I see
Traceback (most recent call last):
File "/opt/ros/indigo/share/gencpp/cmake/../../../lib/gencpp/gen_cpp.py", line 41, in <module>

ImportError: No module named 'em'
import genmsg.template_tools
File "/opt/ros/indigo/lib/python2.7/dist-packages/genmsg/template_tools.py", line 39, in <module>
import em
The error persists although I have ran both python2.7 -m pip install empy
and sudo apt-get install python-empy
Anyone has any advise?
Thanks
