It’s failing when installing pyzmq. You’re installing it on Linux Mint right? It looks like they don’t package g++ by default, whereas Ubuntu does.
I’m not a C++ programmer these days (haven’t been so for 20+ years!), so I’m not up to speed with which version of g++ is used by default. So to be start with, do this from a terminal window:
sudo apt-get install g++
then run the install script again.
