I got the following errors while trying to deploy my smart contract:

sers-Air:lottery user$ node deploy.js

internal/modules/cjs/loader.js:582

    throw err;

    ^



Error: Cannot find module 'truffle-hdwallet-provider'

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] });

as suggested in the other thread but it didn't work. My github repository:

https://github.com/damianjnc/lottery

I did npm install --save truffle-hdwallet-provider@0.0.3 but now got that error:

users-Air: lottery user$ node deploy.js

Try installing @truffle/hdwallet-provider like this in the console (same location from where you're deploying):

npm install @truffle/hdwallet-provider

Good Luck!

Edit 2020-06-17: As of 2019-08-22, the package truffle-hdwallet-provider@1.0.17 has been deprecated and renamed to @truffle/hdwallet-provider. (Source of reference).

  • It helped but now I got that errors: node:31456) UnhandledPromiseRejectionWarning: Error: Transaction was not mined within 50 blocks, please make sure your transaction was properly send.

  • This is when you're txn is not mined within 50 blocks on Ethereum Blockchain. You can refer to my answer here: [https://ethereum.stackexchange.com/questions/62349/web3-sending-tx-times-out-after-280-seconds-because-network-lag/62401#62401]. I've found an alternative solution for this problem. Give it a try! – itsHarshad Nov 19 '18 at 11:25

UPDATE:

truffle-hd-wallet provider has been depreacted: https://www.npmjs.com/package/truffle-hdwallet-provider

Instead use @truffle/hdwallet-provider: https://www.npmjs.com/package/@truffle/hdwallet-provider

After this @truffle/hdwallet-provider will be successfully installed - then reference in required file as follows:

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

I had this problem. What worked was replacing the "truffle-hdwallet-provider" in the require method argument at here: const HDWalletProvider = require('truffle-hdwallet-provider');

with @truffle/hdwallet-provider

const HDWalletProvider = require('@truffle/hdwallet-provider');

and truffle compile finally worked.

But make sure you install it first: run this first:

$ npm install @truffle/hdwallet-provider
