I get this error as well. In the instructions it "When using pyCEC as a network client, libcec is not needed" but when I run the command python3 -m pycec is instantly errors out because it is not there. @konikvranik can you advise and possible update the instructions?

Also by default when installing libcec it puts it in python2.7 but it looks like pycec is designed for python3.

I was able to get it to work but again it does require libcec. If you look at this comment I explain how I was able to get it to work: https://github.com/konikvranik/pyCEC/issues/50#issuecomment-421468331

codymhorton, please guide some steps as i am not sure of the fix.

So the comment I linked to mentions installing someone else's repo. I'm installing for rasberry pi so I used this documentation: https://github.com/Pulse-Eight/libcec/blob/master/docs/README.raspberrypi.md

The instructions are:

sudo apt-get update sudo apt-get install cmake libudev-dev libxrandr-dev python-dev swig cd git clone https://github.com/Pulse-Eight/platform.git mkdir platform/build cd platform/build cmake .. make sudo make install cd git clone https://github.com/blkeller/libcec.git (this is the line that changes) mkdir libcec/build cd libcec/build cmake -DRPI_INCLUDE_DIR=/opt/vc/include -DRPI_LIB_DIR=/opt/vc/lib .. (when you run this you'll notice it says Python3 instead of 2.7) make -j4 sudo make install sudo ldconfig

Once you do this it install in Python3 packages so you can run python3 -m pycec without the error.
