[英]Why do I get the error "Method eth_maxPriorityFeePerGas not supported" when I try to run Web3py with Ganache?
[英]ValueError: Method eth_maxPriorityFeePerGas not supported, web3.py with ganache
我正在使用web3.py
运行以下代码:
transaction = SimpleStorage.constructor().buildTransaction(
{"chainId": chain_id, "from": my_address, "nonce": nonce}
)
我遇到了以下错误:

我该如何解决?
这是来自新版 web3.py 的问题。
您需要将gasPrice
添加到您的交易中,如下所示:
transaction = SimpleStorage.constructor().buildTransaction(
{"chainId": chain_id, "gasPrice": w3.eth.gas_price, "from": my_address, "nonce": nonce}
)
这是由于 EIP1559 更改,以及 web3.py 更新的更改。
