Build Error

[nathanziarek]

Followed the directions to install g++ 4.8 as well as wiringPi, but still having issues installing this node component.

I'm not competent enough in this type of software to understand what's going on, although nothing jumps out at me. I'd guess it's a node-gyp issue, which another user mentioned, but I don't understand how to implement his proposed solution

I'm also seeing this error on install.

> node -v
v11.6.0
> npm  -v
6.5.0

I'm facing the same error too. Any solution for that yet?

I just managed to get this to work by using v8 of node. npm install -g n n v8.16.1
