I am trying to run this code with node and bitcoinjs-lib but I keep getting missing lib.

Any idea what am I missing?

I am on a Windows Server 2016. I try to create a P2SH address by hashing a redeemScript.

// OP_HASH160 {scriptHash} OP_EQUAL
var bitcoin = require('bitcoinjs-lib')
var bscript = require('../../script')
var types = require('../../types')
var typeforce = require('typeforce')
var OPS = require('bitcoin-ops')

function check (script) {
  var buffer = bscript.compile(script)

  return buffer.length === 23 &&
    buffer[0] === OPS.OP_HASH160 &&
    buffer[1] === 0x14 &&
    buffer[22] === OPS.OP_EQUAL
check.toJSON = function () { return 'scriptHash output' }

function encode (scriptHash) {
  typeforce(types.Hash160bit, scriptHash)

  return bscript.compile([OPS.OP_HASH160, e216c9ev2d0drec3xxxxxxxxxxxxxxa3b5576d9176, OPS.OP_EQUAL])

function decode (buffer) {
  typeforce(check, buffer)

  return buffer.slice(2, 22)

module.exports = {
  check: check,
  decode: decode,
  encode: encode

Error is this below, but couldn't find this lib 'script'.

Error: Cannot find module '../../script'

Your file is in the directory:


while the script module is in


The relative path between these two would be ./src/script while your file is prescribing to find it in ../../script. Once you correct the relative path, your program should be able to find the module.

  • I was trying to do that, but the only 'script' I could find is a .js file under the subfolder /src. Here are some screenshots. i.imgur.com/F8PMdmH.png i.imgur.com/1fgdo6U.png Maybe I am entering the wrong path or that is not the .js file required?

  • And what is the location of your file?
