node-rdkafka: Error: librdkafka.so.1: cannot open shared object file: No such file or directory

Environment Information

• OS: Ubuntu 18.4
• Node Version: 9.0.0 and 10.7.0
• NPM Version: 5.5.1
• node-rdkafka version: 2.4.1

Steps to Reproduce

$ cat package.json 
{
  "name": "test-rdkafak",
  "scripts": {
    "test": "node test.js"
  },
  "devDependencies": {
    "node-rdkafka": "^2.3.4"
  }
}

$ cat test.js 
var Transform = require('stream').Transform;

const Kafka = require('node-rdkafka');
var stream = Kafka.KafkaConsumer.createReadStream({
  'metadata.broker.list': 'localhost:9092',
  'group.id': 'librd-test',
  'socket.keepalive.enable': true,
  'enable.auto.commit': false
}, {}, {
  topics: 'test',
  waitInterval: 0,
  objectMode: false
});

stream.on('error', function(err) {
  if (err) console.log(err);
  process.exit(1);
});

stream.pipe(process.stdout);

stream.on('error', function(err) {
  console.log(err);
  process.exit(1);
});

stream.consumer.on('event.error', function(err) {
  console.log(err);
})

It seems to install, but not sure. See install log in comment below.

$ npm install

$ npm ls

The library it says it can’t find does seem to have been built, is this a configuration issue?

$ find | grep librdkafka.so.1
./node_modules/node-rdkafka/build/deps/librdkafka.so.1
./node_modules/node-rdkafka/deps/librdkafka/src/librdkafka.so.1

$ npm run test
