NWJS doesn't work properly with GRPC for Node.js

NWJS doesn’t work with GRPC for Node.js, Run it with Node.JS directly just act as normal.

• State which version are you using Version 0.15.4
• State which OS version are you running with OS X El Captian
• Provide a reproducible case if possible Install GRPC node.js module in the project folder. $ npm intall grpc and run the application that using GPRC via nwjs.
• Error message

GRPC is a native module written in C/C++. Did your rebuild it with node-pre-gyp? If not, please install latest nw-gyp with NPM and rebuild with following command:

cd node_modules/grpc
./node_modules/.bin/node-pre-gyp rebuild --runtime=node-webkit --target=0.15.4 --target_arch=x64

Or you can build grpc at the time of installing it with NPM by using following command:

npm install grpc --build-from-source --runtime=node-webkit --target=0.15.4 --target_arch=x64

@black Sorry I have no computer has Windows installed and no experiences with it. Just follow the ghostoy’s instruction and tell what happened, maybe someone could help. 😉

BTW, as mentioned that gRPC is a native module that needs to be recompiled on each platform and each version upgrade. So NWJS --> WebSocket to gRPC gateway (very easy to be implemented by Go) --> gRPC backend may be a better solution.
