我的APP.js程式碼

我的 Truffle.js 程式碼

module.exports = {
 networks: {
   development: {
     host: "localhost",
     port: 8545,
     network_id: "*" // Match any network id
   }
 }
};

我試過以下這些沒用

1）我們完全刪除了建構文件夾

並重新執行

> > 松露遷移——重置 > > >

（未成功）

2）我已經用這兩個命令檢查重新編譯和部署沒有用

> > 松露編譯松露遷移 > > >

（沒用）

3）誰能解釋這個錯誤在說什麼？什麼是乙太坊中的文物 沒有幫助我請幫助我

Truffle 的預設開發埠9545是

✗ truffle develop
Truffle Develop started at http://127.0.0.1:9545/

Accounts:
(0) 0x627306090abab3a6e1400e9345bc60c78a8bef57
...

為了在本地部署到 Truffle 的開發環境，試試這個：

• 將 9545 作為development網路埠
• truffle develop在一個終端中執行
• 跑進truffle migrate --reset --network development另一個
