Teach me how to upgrade cordova on both PC and Mac

I am currently using VS2017 on PC, and attempting to release via cordova a phone game. It used to work fine but with new android and ios updates and vs updates everything stopped working. I would require someone to explain and resolve the following: 1. Explain/write down steps on how to update ios, android and VS to newer versions (for cordova puposes) 2. Get my game project compiling in a single step from my PC to both android and ios (assuming code compiles without errors)
