tests/integration/test_lottery_integration.py:17: ValueError

Question

在运行测试时，我会得到以下错误：

def test_can_pick_winner():
        if network.show_active() in LOCAL_BLOCKCHAIN_ENVIRONMENTS:
            pytest.skip()
        lottery = deploy_lottery()
        account = get_account()
        lottery.startLottery({"from": account})
        lottery.enter({"from": account, "value": lottery.getEntranceFee()})
        lottery.enter({"from": account, "value": lottery.getEntranceFee()})
        fund_with_link
>       lottery.endLottery({"from": account})
E       ValueError: Gas estimation failed: 'execution reverted'. This transaction will likely revert. If you wish to broadcast, you must set the gas limit manually.

我也遇到了同样的问题，我更改了vrf_coordinator =‘0xb3dCcb4Cf7a26f6cf6Cf6Cf5A73875B7BC655B’，并在brownie-config.yaml文件中验证= false。因为这是vrf合同版本1 https://docs.chain.link/docs/vrf-contracts/v1/的地址.这对我有用！
