You need to sign the transaction you can do it by

eosConfig = {keyProvider: ['YOUE_PRIVATE_KEY']} let eos = Eos(eosConfig) eos.transaction(tr => { tr.newaccount({ creator: 'eosio', name: 'account1', owner: pubkey, active: pubkey }) \.then( (resp) =>{ console.log("EOS resp ", resp);});

As you are on localnet then you need only one parameter to pass in eosConfig which is keyProvider.
