lcm-python: No module named 'lcm' #348

Open dlee640 opened 3 years ago

dlee640 commented 3 years ago

I know this question was asked in this thread, where most people responded to the solution of going into lcm-python directory and running...

$ python setup.py install or $ python3 setup.py install

This solution did not work for me, and I think it is the issue with python and lcm path, or something else that I am not aware of. I am posting the results of running cmake, make, and make install below.

This is the result of running $ cmake ..

It seems like cmake command returns warnings related to GLib2, Doxygen, Java, Lua, and Go. Could this lead to a python importation error? Please guide me in correct direction. :)

Thank you.

It's been a while since you posted this question, but I had success with cmake -DPYTHON_EXECUTABLE=$(which python3) ..
