node-gyp fails with node 12.0, many Utf8Value errors

[markamccann]

• Node Version: node 12.0.0 and npm 6.7.0
• Platform: macOS 10.14.4 (Mojave)
• Compiler: Apple LLVM version 10.0.1 (clang-1001.0.46.4)
• Module: trying to install boost-geospatial-index which compiles with node-gpy

Verbose output (from npm or node-gyp):

.node-gyp/12.0.0/include/node/v8.h:3002:5: note: candidate constructor not viable: no
      known conversion from 'v8::Local<v8::Value>' to 'const v8::String::Utf8Value' for 1st argument
    Utf8Value(const Utf8Value&) = delete;

In short, all of the many deprecation warnings that have been spewing out when using node-gyp up to node version 11.14 are now errors in 12.0. Biggest offender seems to be 'Utf8Value'

You’ll need to take this up with boost-geospatial-index, which will need to update to be compatible with Node.js 12. If it’s using nan then it needs to be using nan 2.13.2.

Thanks. That occurred to me after I posted.
