raise ValueError(‘Explorer API not set for this network’) ValueError: Explorer API not set for this network

我在 brownie 中執行此程式碼： brownie run scripts/deploy.py –networks Rinkeby

deploy.py:

from brownie import network, config, accounts
from brownie import FundMe

def deploy_fund_me():
   account = get_account()
   fund_me = FundMe.deploy({"from": account},publish_source=True)
   print(f"contract deployed to {fund_me.address}")


def get_account():
   if network.show_active() == "development":
       return accounts[0]
   else:
       return accounts.add(config['wallets']['from_key'])



def main():
   deploy_fund_me()

它與您的合約程式碼無關，否則將無法編譯。

如果您的 brownie-config.yaml 設置名稱不匹配，您將收到錯誤消息。那麼唯一的可能就是publish_source=True

刪除publish_source=True. 嘗試不發布。如果您在開發網路上，etherscan 將不知道您的開發網路

我也遇到了這個問題。關於幫助的任何建議？我的 brownie-config.yaml 文件似乎沒問題：

網路：預設：開發 rinkeby：eth_usd_price_feed：‘0x8A753747A1Fa494EC906cE90E9f37563A8AF630e’
