Contracts in NPM @org/dep scoped dependencies don't resolve

[cag]

I have

{
    "solidity.packageDefaultDependenciesContractsDirectory": "",
    "solidity.packageDefaultDependenciesDirectory": "node_modules"
}

in my settings and am trying to import contracts from a scoped package, but am getting an error: Source "@org/dep/contracts/Dependency.sol" not found: File import callback not supported

[juanfranblanco]

@cag can you post a sample of your code and project structure including dependencies thanks

[juanfranblanco]

I have actually seen the issue now on Macs, I'm investigating

[juanfranblanco]

@cag I have tested this in Linux, Mac and Windows.. and I have reproduced it, although eventually just changing the settings and restarting vscode has solved the issue.

[chanhosuh]

Any workaround for this? Changing the settings and restarting isn't fixing it for me. :(

[juanfranblanco]

@chanhosuh what settings are you using?

[chanhosuh]

@juanfranblanco here are my extension-specific settings... I put them both into user and workspace settings.

"solidity.linter": "solhint",
"solidity.packageDefaultDependenciesContractsDirectory": "contracts",
"solidity.packageDefaultDependenciesDirectory": "node_modules",
"solidity.compileUsingRemoteVersion": "v0.6.6+commit.6c089d02",
"solidity.enabledSolium": false

Let me know if anything else would be helpful.

I tried multiple versions going back more than a year, and the problem seems to persist. Interestingly, only the latest versions show red marks around the import; the earlier versions error on the import but do not show the red.

[juanfranblanco]

And your imports? you may need to remove the "contracts" from packageDefaultDependenciesContractsDirectory and use "" instead.

[chanhosuh]

imports are:

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

But... your advice of removing "contracts" worked! :). So strange.

[juanfranblanco]

Yeah mainly that setting is to remove the need to write "contracts" in the import path.

[deluca-mike]

I am getting an error with for import "merkle-trees/libraries/memory/bytes32/standard/merkle-library.sol";

where merkle-trees is in project_root/node_modules

with settings

"solidity.packageDefaultDependenciesContractsDirectory": "",
"solidity.packageDefaultDependenciesDirectory": "",

Obviously I don't have these set correctly, but its quite unclear how to set these.

Any tips?

[juanfranblanco]

@deluca-mike sorry I have just seen this you should have "solidity.packageDefaultDependenciesDirectory": "node_modules" as the dependencies directory

[v1rtl]

Still happens with

  "solidity.packageDefaultDependenciesContractsDirectory": "",
  "solidity.packageDefaultDependenciesDirectory": "node_modules"

[juanfranblanco]

@talentlessguy This is not an issue normally as it is also the default, the only thing I can think is that your node_modules in the root folder.

[v1rtl]

@juanfranblanco my node_modules is in the root. I tried with pnpm, npm and yarn. None worked :(

[juanfranblanco]

@talentlessguy super strange. This is an example structure:

Edit: My settings are the global / default ones for those, you might have overridden them in your workspace?

[v1rtl]

@juanfranblanco nope I have them set globally and have no .vscode folder in my project.

if this helps, this is my contract code:

// SPDX-License-Identifier: MIT

contract MyNFT is ERC721, Ownable {
    struct Metadata {
        string title;
        string picture;
        string audio;
    }

    event Mint(Metadata metadata);
    event Claim(uint256 id);

    uint256 public constant MAX_TOKENS = 50;

    uint256 private constant PRICE = 50000000000000000;

    bool private _isSaleActive = true;

    using SafeMath for uint256;

    mapping(uint256 => Metadata) id_to_nft;

    using Counters for Counters.Counter;

    Counters.Counter private _tokenIdCounter;

    constructor() ERC721("MyNFT", "MNFT") {}

    // Mint NFT and increment ID
    function safeMint(address to) public onlyOwner {
        uint256 id = _tokenIdCounter.current();
        _safeMint(to, id);
        _tokenIdCounter.increment();
    }

    function _baseURI() internal pure override returns (string memory) {
        return ;
    }

    function tokenURI(uint256 tokenId)
        public
        view
        override(ERC721)
        returns (string memory)
    {
        return super.tokenURI(tokenId);
    }

    // Mint an NFT and add metadata to it
    function mint(
        string memory title,
        string memory picture,
        string memory audio
    ) public onlyOwner returns (uint256) {
        uint256 tokenId = _tokenIdCounter.current();

        Metadata memory metadata = Metadata(title, picture, audio);

        id_to_nft[tokenId] = metadata;

        safeMint(msg.sender);

        emit Mint(metadata);

        return tokenId;
    }

    // Claim and mint NFT
    function claim(uint256 id) external payable {
        require(msg.value == PRICE, "Claiming an NFT costs 0.05 ETH");
        require(_tokenIdCounter.current() <= MAX_TOKENS, "Sold out!");

        // Transfer to seller
        safeTransferFrom(address(this), msg.sender, id);

        emit Claim(id);
    }

    // Toggle sale mode
    function toggleSale() public onlyOwner returns (bool) {
        _isSaleActive = !_isSaleActive;
        return _isSaleActive;
    }

    // Check if sale is active
    function isSaleActive() public view returns (bool) {
        return _isSaleActive;
    }

    // withdraw bobux
    function withdraw() public onlyOwner {
        uint256 balance = address(this).balance;
        payable(msg.sender).transfer(balance);
    }

    function transferTo(address acc, uint256 id) public onlyOwner {
        safeTransferFrom(msg.sender, acc, id);
    }
}

@talentlessguy ^^^

[v1rtl]

@juanfranblanco thanks, testing right now

could the issue be that my contracts in the contracts folder? maybe bc of this?

[juanfranblanco]

No that should not be an issue, i have included the workspace settings to override the global just in case.

[juanfranblanco]

[juanfranblanco]

@talentlessguy although you shouldn't, have you tried to restart it?

[v1rtl]

@juanfranblanco i found it out. it didn't work when i have it in a workspace with multiple projects. when opening directly it works.

but it should work for multiple projects in a workspace imo

thanks tho

[juanfranblanco]

@talentlessguy thanks, yes it does not work with multiple workspaces, those were introduced much later, so it will break a lot of stuff, I think project files will be the way forward. But that requires to everyone agree to the format.

[ErrorEater]

I have the same issue: For "openzeppelin" it doesn't complain but for "uniswap" it doesn't recognize the path. If I prepend "node_modules/" for "uniswap" it works.

package.json:

  "dependencies": {
    "@openzeppelin/contracts": "^4.8.1",
    "@uniswap/v2-core": "^1.0.1",
    "@uniswap/v2-periphery": "1.1.0-beta.0"
  }

Thanks for this, have you got any remappings?
