File import callback not supported

[DenGorbachev]

Solved the issue by removing ../ from import paths:

Before (failure):

import "@openzeppelin/contracts-ethereum-package/contracts/token/ERC20/../../Initializable.sol";

After (success):

import "@openzeppelin/contracts-ethereum-package/contracts/Initializable.sol";

Hi @DenGorbachev,

Welcome to the community

If you haven’t seen it already, recommend reading The Future of contracts-ethereum-package.

Hi @sabotagebeats,

Welcome to the community

I am sorry that you have this issue.
If you are using Windows, I suggest running Windows Subsystem for Linux (WSL2): Solidity Smart Contract development on Windows

Please note: All development on the GSN has been moved to the OpenGSN organization.

If you are doing GSN development I recommend joining the OpenGSN Telegram: https://t.me/joinchat/F_BETUjG0Crb2s6mFx1LWA
