Support node 10

[roberttod]

v8::TryCatch has been removed in the v8 engine shipped with node 10 so node-pre-gyp fails in the compilation step. Not sure what the alternative is, but below is the line of code causing the issue. Seems like it would be a fairly simple fix (to someone more intimate with v8 than I am).

change v8::TryCatch to Nan::TryCatch will be ok

Other errors will appear after applying @hyj1991's suggestion:

../src/heap_graph_node.cc:69:24: error: no matching function for call to ‘v8::Object::Has(int32_t&)’

@tlhunter

src/heap_graph_node.cc:69: change if (_cache->Has(_id)) { to if (_cache->Has(Nan::New<Number>(_id))) {

also you can try v8-profiler-next
