Explicitly specify which Node versions are supported in the tutorial

Original report (archived issue) by Anonymous.

The tutorial states that it supports "NodeJS version 4 or higher."
This isn't accurate since I was unable to build gzweb for node v12.16.1 (LTS).
I would get an error stating that "v8::Handle is not defined".

You're talking about this tutorial, right? Thanks for the note. The tutorial has an Edit button on the top. It would be great if you could open a pull request modifying the tutorial to mention the maximum supported version. Thanks!

i think the node v12.6.2 also have the similar mistakes on building .

here the problem i meet now , i can build the project use node version 8.x and 6.x but after building , when i run the gzweb using npm start , the problem comes out such that the

NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 72. Please try re-compiling or re-installing

comes out , when i go back to check the node_module version of every node package, only the node v12.x has the version 72 , however, the module can’t compile using that version which seems the problem is unsolvable for me.

my system info: ros Kinetic

ubuntu 16.04

gazebo v10
