How to solve “More than one instance of bitcore-lib found” error?

0 votes

I am trying to use bitcore-lib to generate bitcoin address and fetch unspent transaction using bitcore-explorer.

The code I am using is as always:

var bitcore = require('bitcore-lib');
var rand_buffer = bitcore.crypto.Random.getRandomBuffer(32);
var rand_number = bitcore.crypto.BN.fromBuffer(rand_buffer);
var privateKay = new bitcore.PrivateKey(rand_number);
var privateKeyWif = privateKay.toWIF();
var address = privateKay.toAddress('testnet');
  privateKeyWif: privateKeyWif,

And the output I am getting is:

{ rand_buffer: <Buffer 55 8b 27 c4 51 87 97 17 9a 7d 1d 72 48 26 e5 83 95 74 5b 3b b1 b4 b5 b6 a7 1c df 9f 18 e6 97 2e>,
  rand_number_hex: <BN: 558b27c4518797179a7d1d724826e58395745b3bb1b4b5b6a71cdf9f18e6972e>,
  rand_number_dec: '38692458332424984226826540178179935156087120588336482991409403810055901845294',
  privateKey: <PrivateKey: 558b27c4518797179a7d1d724826e58395745b3bb1b4b5b6a71cdf9f18e6972e, network: livenet>,
  privateKeyWif: 'Kz5zkBwfiYNkyswsKjot4wWmxHWUZdVMmxf65Z5wLk29ufhxnnQT',
  address: <Address: msTDjA4PmyePSWx2VcaQWoWoQ7gWzU2Kqx, type: pubkeyhash, network: testnet> }

My next code is follows:

var Insight = require('bitcore-explorers').Insight;
var insight = new Insight('testnet');
  if(error) return console.log(error);

I am receiving the following error:

    throw new Error(message);
Error: More than one instance of bitcore-lib found. Please make sure to require bitcore-lib and check that submodules do not
also include their own bitcore-lib dependency.

There is a temp solution here.


line 7:

bitcore.versionGuard = function(version) {

Change it to:

bitcore.versionGuard = function(version) { return;

There is no permanent solution for this problem yet. You can check this:
