Same error here...Have you fixed this?

same problem.

Hi guys after facing many issues I finally could run truffle migrate in my production environment following these steps below:

1. run cmd install with admin rights
2. npm install -g truffle
3. npm install -g windows-build-tools
4. npm install -g node-gyp
5. set npm_config_node_gyp=%appdata%\npm\node_modules\node-gyp\bin\node-gyp.js
6. md your_project_name
7. cd your_project_name
8. npm init -y
9. npm install truffle-hdwallet-provider -s
10. truffle init
11. code your solidity contract
12. configure your 2_deploy_contract.js file
13. configure your truffle-config.js file including the section:
    production: { provider: () => new HDWalletProvider(mnemonic, your rpc endpoint), network_id: 10101010, // This network is yours, in the cloud. gasPrice: 0 // it´s necessary to allow deploy contracts on a PoA network }
14. uncomment these lines in the top of config file const HDWalletProvider = require('truffle-hdwallet-provider'); const fs = require('fs'); const mnemonic = fs.readFileSync(".secret").toString().trim();
15. Create a .secret file in your root project directory including your wallet mnemonic
16. truffle compile
17. truffle migrate --network production

Hope it helps you guys!

This is not a safe fix. But if only for testing purposes, add --unsafe-perm=true --allow-root to the install command.

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

truffle-hd-wallet provider has been deprecated: 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");
