Module is extraneous npm

Question

I obviously check there is connect-privkey-to-provider module in dependencies. However, it keep saying Module 'connect-privkey-to-provider' is extraneous npm and cannot find module 'connect-privkey-to-provider'

What's wrong with my code?

Error

@YegorZaremba I'm sorry for late response, you can see it by `git clone https://github.com/kkagill/addition-game-starter.git` and paste **truffle.js** code which I've added on my question and then excute `truffle deploy --network klaytn` in terminal! — 1Sun, May 22 '19 at 01:44

Your code works fine in my environment. Try to do these:

Remove node_modules
Remove package-lock.json
Update truffle package npm update -g truffle
Reinstall, using command npm i

After that just change solidity version in contracts folder

pragma solidity ^0.5.0;

When I tried to do the first step `remove node_modules`, it kept causing errors.. I uploaded the image showing the error part – 1Sun May 24 '19 at 11:35
use this command: `rmdir node_modules` and `del package-lock.json` – Yegor Zaremba May 24 '19 at 13:37
