core.addProviders n'est pas une fonction

J'essaye d'exécuter mon fichier deploy.js qui a le code:

core.addProviders(Web3);

module.exports = Web3;

Et quand j'exécute node deploy.js code>: il lance l'erreur maintenant, qui fonctionnait bien avant, L'erreur est indiquée ci-dessous:

et le fichier web3.js (qui se trouve à l'intérieur de node_modules) a le code:

const HDWalletProvider = require("truffle-hdwallet-provider");
const Web3 = require("web3");
const compiledFactory = require('./build/CampaignFactory.json');
//const web3 = new Web3(provider);

const provider = new HDWalletProvider(
  "[12 word mnemonic]",
  "[rinkeby api from infura]"
);

const web3 = new Web3(provider);

const deploy = async () => {
  const accounts = await web3.eth.getAccounts();

  console.log("Attempting to deply from account", accounts[0]);
  const result = await new web3.eth.Contract(JSON.parse(compiledFactory.interface))
    .deploy({ data: compiledFactory.bytecode })
    .send({ gas: '1000000', from: accounts[0] });

  //console.log(interface);
  console.log("Contract deployed to", result.options.address);
};
deploy();

En bref, pour contourner un bogue, nous devons ajouter deux lignes supplémentaires et changer une ligne de code dans notre fichier de test. Apportez les trois modifications ci-dessous:

const assert = require('assert');
const ganache = require('ganache-cli');
const Web3 = require('web3');

// UPDATE THESE TWO LINES RIGHT HERE!!!!! <-----------------
const provider = ganache.provider();
const web3 = new Web3(provider);

const { interface, bytecode } = require('../compile');

let accounts;
let inbox;

beforeEach(async () => {
// Get a list of all accounts
accounts = await web3.eth.getAccounts();
// Use one of those accounts to deploy the contract
inbox = await new web3.eth.Contract(JSON.parse(interface))
  .deploy({ data: bytecode, arguments: ['Hi there!'] })
  .send({ from: accounts[0], gas: '1000000' });

// ADD THIS ONE LINE RIGHT HERE!!!!! <---------------------
inbox.setProvider(provider);
 });

describe('Inbox', () => {
   it('deploys a contract', () => {
      assert.ok(inbox.options.address);
     });
   it('has a default message', async () => {
      const message = await inbox.methods.message().call();
      assert.equal(message, 'Hi there!');
     });
});

Assurez-vous que votre geth est également exécuté dans le terminal. Exécutez simplement geth sur votre terminal. Votre web3 est la version "web3": "^ 1.0.0-beta.37" dans package.json
