ReferenceError：未定義歡迎程序

這是我的腳本deploy.js：

const main = async () => {


 // We get the contract to deploy
 const Transactions = await hre.ethers.getContractFactory("Transactions");
 const transactions = await Transactions.deploy();

 await greeter.deployed();

 console.log("Greeter deployed to:", greeter.address);
}

const runMain = async() => {
 try {
   await main();
   Process.exit(0);
 } catch (error) {
   console.error(error);
   process.exit(1);
 }
}

runMain();

這是我的腳本hardhat.config.js：

// This is a sample Hardhat task. 
// https://eth-ropsten.alchemyapi.io/v2/Bn5tm9fX90ET1hKwb76lKJB0rzU3JBi2

require("@nomiclabs/hardhat-waffle");


module.exports = {
 solidity: '0.8.0',
 networks: {
   ropsten: {
     url: "https://eth-ropsten.alchemyapi.io/v2/Bn5tm9fX90ET1hKwb76lKJB0rzU3JBi2",
     accounts: ["63b598044c3cce8d656............b7c64beb17eb1687aebbefc5cac8a"]
   }
 }
}

這是我的solidity合約腳本：

pragma solidity >=0.6.0 <0.9.0;

contract Transactions {
   uint256 transactionCount;

   event Transfer(

       emit Transfer(

   }

   function getAllTransactions()
       public
       view
       returns (TransferStruct[] memory)
   {
       return transactions;
   }

   function getTransactionCount() public view returns (uint256) {
       return transactionCount;
   }
}

以下是我在嘗試編譯時收到的錯誤消息：

PS C:\Users\Temitope\Desktop\kredar\smart_contract> npx hardhat run scripts/deploy.js --network ropsten
ReferenceError: greeter is not defined
at main (C:\Users\Temitope\Desktop\kredar\smart_contract\scripts\deploy.js:8:3)
at processTicksAndRejections (node:internal/process/task_queues:96:5)
at runMain (C:\Users\Temitope\Desktop\kredar\smart_contract\scripts\deploy.js:15:5)

請讓我知道我做錯了什麼以及如何解決它。

刪除這些行deploy.js應該沒問題

await greeter.deployed();
console.log("Greeter deployed to:", greeter.address
