Я настраиваю новую локальную тестовую сеть (Ganache), пишу UNI TEST в MOCHA и web3.Мы настроили библиотеку для подключения ABI к тестовой сети с именем Web3.Где мне нужно установить кодировку / кодировки? »

                          [HELLO.TEST.JS]
//import web3 from 'web3';
const assert= require('assert');
const ganache = require('ganache-cli');
const Web3 = require('web3');
console.log(Web3);return;
const provider = ganache.provider();
console.log(provider);return;
const web3 = new web3(provider);
console.log(web3);return;
const { interface, bytecode } = require('../compile');
let accounts;
let hello;
const INITIAL_THINGS = 'Hi there!';
beforeEach(async () => {
    // get a list of all accounts
    accounts = await web3.eth.getAccounts();
    console.log(JSON.parse(interface));return;
    hello = await new web3.eth.Contract(JSON.parse(interface))
        .deploy({ data: bytecode, arguments: [INITIAL_THINGS] })
        .send({ from: accounts[0], gas: '1000000' })
    hello.setProvider(provider);
})
describe('Hello', () => {
    it('deploys a contract', () => {
        assert.ok(hello.options.address);
    });
    it ('has a default message', async () => {
        const message = await hello.methods.getMessage().call();
        assert.equal(message, INITIAL_THINGS);
    });
    it('can change the message' , async()=>{
        await hello.methods.setMessage('bye').send({from: accounts[0]});
        const message = await hello.methods.getMessage().call();
        assert.equal(message, 'bye');
    });
})

и файл PACKAGE.JSON имеет код: 

                             [PACKAGE.JSON]
{
  "name": "newpackage",
  "version": "1.0.0",
  "description": "",
  "main": "compile.js",
  "directories": {
  "test": "test"
  },
  "scripts": {
    "test": "mocha"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "ganache-cli": "^6.4.4",
    "mocha": "^6.1.4",
    "solc": "^0.4.25",
    "web3": "^1.0.0-beta.26"
  }
}

И при запуске он выдает ошибку сейчас, который работал нормально раньше, ошибка показана ниже:

    core.addProviders(Web3);
     ^
