5 years ago i am using v4.0.3
"bitcoinjs-lib": "^4.0.3"

5 years ago Then you have a dependency overlap with something.
One of your dependencies must be using v3 as a dependency, and your app is getting confused which one you are using.

5 years ago Now i uninstalled the module and installed again
But now i am getting this error
var root = bitcoin.HDNode.fromSeedBuffer(seed, bitcoin.networks.testnet); ^
TypeError: Cannot read property 'fromSeedBuffer' of undefined
at Object.
can u plz help me..
My code:
const bip39 = require('bip39') const bip32 = require('bip32') const bitcoin = require('bitcoinjs-lib') const TESTNET = bitcoin.networks.testnet
var mnemonic = bip39.generateMnemonic(); var seed = bip39.mnemonicToSeed(mnemonic); var root = bitcoin.HDNode.fromSeedBuffer(seed, bitcoin.networks.testnet);
//root can be transformed to your xpub and xprv var xprv = root.toBase58(); var xpub = root.neutered().toBase58();

5 years ago HDNode is removed in v4. it only exists in v3.
You need to work on your app / your dependencies. it looks like you app is using a mixture of v3 only and v4 only methods.
bitcoin.HDNode was changed to bitcoin.bip32 and it has fromSeed instead of fromSeedBuffer

5 years ago yes i am trying fromSeedBuffer with v3 now my issue is fixed ..
Thank you
