@User I think it's important to note that there is no single analogue design environment. That's a large part why you cant find an easy installation command or consistent instructions. It's kind of like some with money to spend on traditional tools saying "what do I need to install to design ICs?" well, do you want to use virtuoso, tanner, synopsys. Oh you want to use virtuoso, do you want ADE assembler or explorer or verifier? What level of layout license do you need? Do you use Calibre for DRC/LVS or assura? etc. etc. etc. So the reason there isn't a clean answer is the question is not formed correctly
