我正在尝试使用 ethers.js 库和 Ganache 部署合约，遵循 Patrick Collins 的课程，但我遇到了 JsonRpcProvider 的问题。我已按照提供的代码设置了环境变量，但我不断收到错误。详情如下：
const ethers = require("ethers")
// const solc = require("solc")
const fs = require("fs-extra")
require("dotenv").config()
async function main() {
// First, compile this!
// And make sure to have your ganache network up!
// The old way can be seen below:
// let provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
// On ether 6 and above, you should use like this
let provider = new ethers.JsonRpcProvider(process.env.RPC_URL)
// let provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
let wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider)
// const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf8");
// let wallet = new ethers.Wallet.fromEncryptedJsonSync(
// encryptedJson,
// process.env.PRIVATE_KEY_PASSWORD
// );
// wallet = wallet.connect(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()
// const contract = await contractFactory.deploy({ gasPrice: 100000000000 })
const deploymentReceipt = await contract.deployTransaction.wait(1)
console.log(`Contract deployed to ${contract.address}`)
// console.log("Here is the transaction:")
// console.log(contract.deployTransaction)
// console.log("Here is the receipt:")
// console.log(deploymentReceipt)
// const nonce = await wallet.getTransactionCount()
// tx = {
// nonce: nonce,
// gasPrice: 100000000000,
// gasLimit: 1000000,
// to: null,
// value: 0,
// data: "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",

我尝试通过将服务器主机名更改为“vEthernet (WSL)”来解决该问题，因为我正在使用连接到 WSL 的 VSCode。尽管进行了这样的调整，错误仍然没有解决。
在以太6中，尝试改变
const deploymentReceipt = await contract.deployTransaction.wait(1)
到
await contract.waitForDeployment(1)
它对我有用。
