Open Zeppeelin contracts not found (on windows)

[martinoss]

Wanted to check out the casino-dapp and followed the steps from the readme. When trying to run the migrate command, I got errors that contracts from open zeppelin could not be found. Guess its the way the drive is spelled.

I was able to fix it by omitting ../node_modules/ from the import statements and make it look like this:

import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/math/SafeMath.sol";

If it still works on other platforms like this, I suggest to also omit ../node_modules/ in this sample.

C:\Code\GitHub\demo-apps\casino-dapp\truffle (main -> origin) ([email protected])
λ truffle console
truffle(ganache)> migrate
