Hi, In GSN tutorial, When compiling the Counter contract(oz compile) I got the following errors(in short): Compiling contracts with solc 0.5.11 (commit.c082d0b4) Compilation errors: @openzeppelin/contracts-ethereum-package/contracts/GSN/GSNRecipient.sol:4:1: ParserError: Source "@openzeppelin/con…

OK, Thanks. I just wanted to do it on Windows because I usually do many things with Windows. :sweat_smile:

Hi @swkim109 , I use Windows (except for smart contract development) :smile: Did you get a chance to try with the latest version of truffle? If it is still occurring we should report to Truffle as it appears to be Windows specific.

I have upgraded to Truffle 5.0.36 but same error(File import callback not supported) occurred on Windows 10. In truffle, importing files with relative path works fine. For example, I write the ERC20 token contract: pragma solidity ^0.5.0; import "openzeppelin-solidity/contracts/token/ERC20/ERC20M…

I also have this issue on Win10, following the docs learn example: https://docs.openzeppelin.com/learn/developing-smart-contracts Edit: I changed to the wsl-ubuntu terminal, installed nvm and node, and now the npx oz compilation works fine on my project with no callback errors.

Hi @viltiki , I am glad you were able to resolve. I use Windows Subsystem for Linux too. For community members coming across this, the options for Solidity Smart contract development on Windows are: [image] Solidity Smart Contract development on Windows Guides and Tutorials …

just heads up I just filed an issue with pull request to support it without WSL since the connection in WSL is not really stable in my experience, so I still prefer use it natively. https://github.com/OpenZeppelin/openzeppelin-sdk/issues/1558

Hi @yurenju , Welcome to the community :wave:. Thanks for creating the issue. I have used WSL and now use WSL2 without issues, so sorry to hear that you have problems with it.

I definitely will try WSL2 when the upgrade rolling on my laptop :crossed_fingers:

@abcoathup I’m having the same Issue: Source “@openzeppelin/contracts-ethereum-package/contracts/GSN/GSNRecipient.sol” not found: File import callback not supported with: import “@openzeppelin/contracts-ethereum-package/contracts/GSN/GSNRecipient.sol”; I just follow the tutorial https://docs.ope…

Hi @Gabriel1590 , Welcome to the community :wave: Please see this post for how to upgrade the contract to Solidity 0.6 and use OpenZeppelin Contracts Ethereum Package v3. [image] Upgradeable GSN enabled Counter.sol has DeclarationError: Identifier not found or not unique Support …
