File outside of allowed directories error.

Hi, I was trying to flat a very simple contract just to test the library and python requirements:

pragma solidity ^0.4.24;

import "../node_modules/openzeppelin-solidity/contracts/ownership/Ownable.sol";
import "../node_modules/openzeppelin-solidity/contracts/token/ERC20/StandardBurnableToken.sol";

contract myToken is StandardBurnableToken, Ownable {
    string public name = "";
    string public symbol = "";
    uint8 public decimals = 18;
}

and I get this:

solidity_flattener contracts/MyToken.sol
contracts/MyToken.sol:3:1: Error: Source "node_modules/openzeppelin-solidity/contracts/ownership/Ownable.sol" not found: File outside of allowed directories.
import "../node_modules/openzeppelin-solidity/contracts/ownership/Ownable.sol";

The $ truffle compile works well.

Thank you for the help.

@XertroV Yes i noticed it. Actually I don’t know maybe I’m missing something else but it worked. Give a look to those two tracebacks. The first one worked the second one nope and the diff is only the solc prefix.

Have a nice day!

@andreafspeziale glad you got it working.

It’s weird that adding solc to the start worked… I wouldn’t expect it to given this line: https://github.com/BlockCatIO/solidity-flattener/blob/53b01d1db12a5ef4dfe35adf4bd6e4f73d90d0f8/flattener/core.py#L93

In any case 👍
