gyp fails with: error: no matching function for call to ‘v8::Value::ToUint32()’

[vhammond-inap]

After running npm install iptrie with node 10.15.2 and npm 5.8.0

../src/iptrie.cc:181:42: error: no matching function for call to ‘v8::Value::ToUint32()’
int prefix_len = args[1]->ToUint32()->Value();

I patched my local like so

•  int prefix_len = args[1]->ToUint32()->Value();
  

•  int prefix_len = args[1]->IntegerValue();
  

on lines 182 and 211 (diff attached)
