Web3js Send transaction is broken?

UPDATE: I am not really familiar with NPM, so i guess that is the problem. I only installed NPM, what else must i do in order to start the application succesfully?
I’ve installed web3js and i am using this script from github ( https://gist.github.com/raineorshine/c8b30db96d7532e15f85fcfe72ac719c )
const Web3 = require(‘web3’)
const Tx = require(‘ethereumjs-tx’).Transaction

// connect to Infura node
const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/INFURA_KEY'))

// the address that will send the test transaction
const addressFrom = '0x1889EF49cDBaad420EB4D6f04066CA4093088Bbd'
const privateKey = new Buffer('PRIVATE_KEY', 'hex')

// the destination address
const addressTo = '0x1463500476a3ADDa33ef1dF530063fE126203186'

// construct the transaction data
// NOTE: property 'nonce' must be merged in from web3.eth.getTransactionCount 
// before the transaction data is passed to new Tx(); see sendRawTransaction below.
const txData = {
  gasLimit: web3.utils.toHex(25000),
  gasPrice: web3.utils.toHex(10e9), // 10 Gwei
  to: addressTo,
  from: addressFrom,
  value: web3.utils.toHex(web3.utils.toWei('123', 'wei')) // thanks @abel30567
  // if you want to send raw data (e.g. contract execution) rather than sending tokens,
  // use 'data' instead of 'value' (thanks @AlecZadikian9001)
  // e.g. myContract.methods.myMethod(123).encodeABI() (thanks @NguyenHoangSon96)

/** Signs the given transaction data and sends it. Abstracts some of the details of 
  * buffering and serializing the transaction for web3.
  * @returns A promise of an object that emits events: transactionHash, receipt, confirmaton, error
const sendRawTransaction = txData =>
  // get the number of transactions sent so far so we can create a fresh nonce
  web3.eth.getTransactionCount(addressFrom).then(txCount => {
const newNonce = web3.utils.toHex(txCount)
const transaction = new Tx({ ...txData, nonce: newNonce }, { chain: 'mainnet' }) // or 'rinkeby'
const serializedTx = transaction.serialize().toString('hex')
return web3.eth.sendSignedTransaction('0x' + serializedTx)

// fire away!
// (thanks @AndreiD)
sendRawTransaction(txData).then(result =>
.on('transactionHash', txHash => {
  console.log('transactionHash:', txHash)
.on('receipt', receipt => {
  console.log('receipt:', receipt)
.on('confirmation', (confirmationNumber, receipt) => {
  if (confirmationNumber >= 1) {
    console.log('confirmations:', confirmationNumber, receipt)
.on('error:', error => {

Obviously i changed infura provider, as well as the keys, but the problem is when i try to run “Node send2.js”

What does this mean? I have no cliue what do these 3 dots mean, can’t google either.
Any advice? Basically i am trying to send a transactin from a server.

It seems like you should add a key word chainId, such as var tx = new Tx(rawTx, {'chain':'ropsten'});, and for more details, you can have a look at the documentation: web3.eth | web3.js 1.0.0 documentation
