^---------------------------------------^
- the code that caused the failure
There is an import in the solidity contract that I try to import another contract. But the program cannot find it.
in my python code:
contract_source_code = open('../contracts/storage/SimpleStorage.sol', 'r').read()
PROJECT_ROOT = os.path.dirname(os.path.dirname(__file__))
compiled_sol = compile_source(contract_source_code, allow_paths=PROJECT_ROOT) # Compiled source code
in my SimpleStorage.sol:
pragma solidity ^0.4.24;
import './interfaces/ISimpleStorage.sol';
