错误：无法估计gas；交易可能会失败或可能需要手动气体限制SERVER_ERROR

Question

我正在尝试在 WSL studio 和 Ganache 上使用 javascript 部署 SimpleStorage Solidity 合约。

我的deploy.js代码是：

const ethers = require("ethers");
const { readFileSync } = require("fs");
const fs = require("fs-extra");
async function main() {
  //
  const provider = new ethers.providers.JsonRpcProvider(
    "http://172.24.176.1:7545"
  );
  const wallet = new ethers.Wallet(
    "0x757b08fac160cc001a4adfebadc26ac10a6e59e2490fda35bce0c35939f265f1",
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy(); //STOP here wait for contract to deploy
  console.log(contract);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

我在终端上尝试了命令“node deploy.js”，出现以下错误：

root@LAPTOP-UFP1511I:~/folder/hh-fcc/ethers-simple-storage-fcc#节点deploy.js 正在部署，请稍候...

有人可以告诉我发生了什么事吗？

Answer 1

尝试这些，选项 2 对我有用

选项 1 -（此后我遇到了不同的错误，但它部署了合约）

https://github.com/ethereum/solidity/issues/13159#issuecomment-1826481491

const overrides = {
    gasPrice: 2000000000, // Can set this >= to the number read from Ganache window
    gasLimit: 6721975, // Use the same gasLimit as read from Ganache window (or a bit higher if still having issue)
};
console.log("Deploying contract, please wait...");
const contract = await contractFactory.deploy(overrides);

选项 2（无需添加覆盖）：

更改solc版本“solc”：“0.8.7-fixed”

更改合约编译指示中的编译器版本 ^0.8.7;
