Unable to get balance with bitcore lib

Unable to get balance with bitcore lib

Using latest version of bitcore lib , want to check balance for making tx but once I include

var explorers =require('bitcore-explorers');

after

var bitcore =require('bitcore-lib');

Error: More than one instance of bitcore-lib found. Please make sure to require bitcore-lib and check that submodules do not also include their own bitcore-lib dependency.

I had a look at this thread

Bitcore = "Error: More than one instance of bitcore-lib found"

but it does not help . When I comment out this part

var bitcore =require('bitcore-lib');

explorer seem to be running but the problem is it always returns 0 for all the wallets . For instance this wallet has fonds wallet testnet fonds

here is the code

const insight = new explorers.Insight();
insight.getUnspentUtxos('mkFPBvd3jbPYn4223SNTneBWHodziU287G', function(err, utxos) {
    console.log(utxos);
    let balance = 0;
    for (var i = 0; i < utxos.length; i++) {
        balance +=utxos[i]['satoshis'];
    }
    console.log('balance:'+ balance);
});

and response is always [] , 0

1) How to check balance using bitcore without conflict with bitcore-lib ?

2) Which is the "web3" (most commonly used for ethereum) node js library for bitcoin ?

Thanks a lot !
