I am just trying to create a HD wallet with web3 and truffle to make receive some ethers. I have installed both of these packages with npm. Inside a node console, I am trying to run this to get a private/public key :
Bip39 = require("bip39");
const mnemonicPhrase = Bip39.generateMnemonic();
const HDWalletProvider = require("@truffle/hdwallet-provider");
Web3 = require('web3');
provider = new HDWalletProvider({
mnemonic: mnemonicPhrase,
providerOrUrl: "http://localhost:8545",
numberOfAddresses: 1,
shareNonce: true,
derivationPath: "m/44'/0'/0'/0/"
});
const web3 = new Web3(provider);
web3.eth.accounts.create()
I am running one piece of code after another and just after I run the provider = new HDWalletProvider(), I get this error:
Error: PollingBlockTracker - encountered an error while attempting to update latest block:

Some people mentioning this error are fixing it with something like testrpc, geth --rpc that is apparently used to send the transaction on the ethereum network, but I don't want to do that, I just need to retrieve the private/public key in web3js. I really don't understand what I need to do to fix this.
