I am trying to run a test script for my smart contract but ganache provider is not being accepted by web3 here is my code.

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

beforeEach(()=>{
  web3.eth.getAccounts()
    .then(fetchedAccounts=>{
      console.log(fetchedAccounts);
    });
});

describe('Inbox',()=>{
  it('deploys a contract',()=>{

  });
});

This is error message

      throw new Error('Please provide an valid Web3 provider');
            ^

  • Current version is 1.0.0-beta.41. There are known problems in 38 and 39, but why use 37??? Feb 7, 2019 at 18:10
