Unable to fix - events.js:183 throw er; // Unhandled 'error' event

Question

I am using a Mac. I am trying to run a simple Twitter stream but I am getting the error events.js:183 throw er; // Unhandled 'error' event. After some googling, it seems like this usually happens when there is already a node process running. I've restarted my computer, reopened the terminal and tried all sorts of different terminal commands.

killall node => No matching processes belonging to you were found

killall -9 node => No matching processes belonging to you were found

ps aux | awk '/node/{print $2}' | xargs kill -9 => kill: 872: No such process

rm -rf node_modules && npm cache clean --force => doesn't work

const Twitter = require('twitter');

const twitter = new Twitter({
  consumer_key: '',
  consumer_secret: '',
  access_token: '',
  access_secret: ''
});

twitter.stream('filter', { track: 'hello' }, function(stream) {
  stream.on('data', function(data) {
    console.log(data.text);
  });
});

Answer 1

The values of access_token and access_secret were incorrect. It wasn't a problem of a different node process already running.
