錯誤：找不到模組“truffle-hdwallet-provider”

嘗試部署我的智能合約時出現以下錯誤：

sers-Air:lottery user$ node deploy.js

internal/modules/cjs/loader.js:582

   throw err;

   ^

users-Air:lottery user$



I also tried to change it to const result = await new web3.eth.Contract(JSON.parse(interface))

.deploy({ data: '0x' + bytecode })

.send({ from: accounts[0] });

正如另一個執行緒中所建議的，但它沒有用。我的 github 倉庫：

https://github.com/damianjnc/lottery

我做npm install --save truffle-hdwallet-provider@0.0.3了，但現在得到了那個錯誤：

users-Air: 彩票使用者$ node deploy.js

嘗試@truffle/hdwallet-provider在控制台中像這樣安裝（與您部署的位置相同）：

npm install @truffle/hdwallet-provider

祝你好運！

***編輯 2020-06-17：*截至 2019-08-22，該軟體包truffle-hdwallet-provider@1.0.17已被棄用並重命名為@truffle/hdwallet-provider. （參考來源）。

更新：

truffle-hd-wallet 提供程序已被棄用： https ://www.npmjs.com/package/truffle-hdwallet-provider

而是使用@truffle/hdwallet-provider： https ://www.npmjs.com/package/@truffle/hdwallet-provider

在此@truffle/hdwallet-provider 將成功安裝之後 - 然後在所需文件中引用如下：

var HDWalletProvider = require("@truffle/hdwallet-provider");
