Compilation of µWebSockets has failed and there is no pre-compiled binary

Question

I am trying to run a local websocket server using nodejs and uws on a linux machine. the npm install uws runs without any error and I can see a uws named folder inside my node_modules. But when I try to create websocket server using following code. It gives me error

/home/suresh/browserstack/node_modules/uws/uws.js:40
            throw new Error('Compilation of µWebSockets has failed and there is no pre-compiled binary ' +
            ^

Error: Compilation of µWebSockets has failed and there is no pre-compiled binary available for your system. Please install a supported C++11 compiler and reinstall the module 'uws'.

Here is my js code:

const WebSocket = require('uws').Server;
var http = require('http');

var server = http.createServer(function(request, response) {});

var wss = new WebSocket({
  server: server,
  path: '/wss'
});

var connCounter = 1;
wss.on('connection', function(ws){
  console.log('new connection');

  ws.id = connCounter;
  ws.on('message', function(message){

  });

  ws.on('close', clearWS);
  ws.on('end', clearWS);
  ws.on('disconnect', clearWS);
  ws.on('error', clearWS);

  function clearWS(e){
    console.log('in clearWS', e);
  }
})

function sendBuffer(ws, buffer){
  if (ws && ws.readyState == 1)
    ws.send(buffer);
}

I looked at /home/suresh/browserstack/node_modules/uws/uws.js:40 and found that a native function is failing due to missing uws_linux_48 file. Below is the added printed error logs statements:

Error: Cannot find module './uws_linux_48'

I searched on the internet and found some github issues and comments but they didn't help.

Here is my system information:

gcc - version 5.5.0
node - v6.14.3
npm - 3.10.10

Tons of thanks in advance
