執行 Truffle 腳本的問題：‘Exchange’ 即智能合約 (SC) 尚未部署到檢測到的網路

我正在關注提供的教程： Truffle 腳本範例

但我已經添加了 ganache、編譯和遷移。在遷移中，我收到以下錯誤：$ truffle exec ts2.js Using network ‘ganache’。

Error: Exchange has not been deployed to detected network (network/artifact mismatch)
   at Object.checkNetworkArtifactMatch (/home/zulfi/.nvm/versions/node/v10.23.3/lib/node_modules/truffle/build/webpack:/packages/contract/lib/utils/index.js:245:1)
   at Function.deployed (/home/zulfi/.nvm/versions/node/v10.23.3/lib/node_modules/truffle/build/webpack:/packages/contract/lib/contract/constructorMethods.js:85:1)
   at process._tickCallback (internal/process/next_tick.js:68:7)

我的松露 2_deploy_contracts.js 是：

const Exchange = artifacts.require("Exchange");

module.exports = function(deployer) {
deployer.deploy(Exchange);
};

教程中提供了 Exchange 合約和腳本，我將腳本命名為 ts2，複製如下：

// Contracts
const Exchange = artifacts.require("Exchange")

// Utils
const ether = (n) => {
 return new web3.utils.BN(
   web3.utils.toWei(n.toString(), 'ether')
 )
}

module.exports = async function(callback) {
 try {
   // Fetch accounts from wallet - these are unlocked
   const accounts = await web3.eth.getAccounts()

   // Fetch the deployed exchange
   const exchange = await Exchange.deployed()
   console.log('Exchange fetched', exchange.address)

   // Set up exchange users
   const user1 = accounts[0]

   // User 1 Deposits Ether
   amount = 2
   await exchange.depositEther({ from: user1, value: ether(amount) })
   console.log(`Deposited ${amount} Ether from ${user1}`)

   //...
 }
 catch(error) {
   console.log(error)
 }

 callback()
}

有人請指導我。

本教程適用於我這個truffle-config.js文件：

module.exports = {

 networks: {
     development: {
     host: "127.0.0.1",     // Localhost (default: none)
     port: 8545,            // Standard Ethereum port (default: none)
     network_id: "*",       // Any network (default: none)
    },
 },

 // Set default mocha options here, use special reporters etc.
 mocha: {
   // timeout: 100000
 },

 // Configure your compilers
 compilers: {
   solc: {
      version: "0.8.4",    // Fetch exact version from solc-bin (default: truffle's version)
   }
 }
};

確保使用正確部署智能合約truffle migrate --reset。

然後，我能夠成功執行truffle exec ts2.js。
