現在加油策略不起作用

當我在合約部署中使用 GasNowStrategy(“fast”) 時，出現錯誤：

   from brownie.network.gas.strategies import GasNowStrategy


def main():
   dev = accounts.add(config["wallets"]["from_key"])
   print(dev)
   print(network.show_active())
   deployed_contract = Bbum.deploy(
       {"from": dev, "gas_price": GasNowStrategy("fast")}
   )

這裡有什麼問題？

錯誤：

   return_value, frame = run(

   return_value = f_locals[method_name](*args, **kwargs)

   return tx["from"].deploy(

   raise VirtualMachineError(e) from None

   raise ValueError(str(exc)) from None
ValueError: Expecting value: line 1 column 1 (char 0)

所以，我了解到GasNowStrategy已經關閉，可能與國內監管政策有關。因此，如果有人遇到此問題，請更改為其他氣體策略。

我正在進行個人修復，但您將不得不在新腳本下模擬_fetch_gasnow 和 network.gas.bases 中的策略，以便您可以更改端點。
