Lesson 4 trying to run deploy.py Error, File outside of allowed directories.

[Oscar-Chung-CKL]

I am trying to run the python file deploy.py which to check and print (compile_sol). However, I keep having the error saying that the source "@chainlink/contracts/src/v0.6/vendor/SafeMathChainLink.sol" is not found and I don't know how to fix the issue

My entire error message is:

FYI, my deploy.py file is:

`from solcx import compile_standard, install_solc # <- import the install_solc method!
install_solc('0.6.0') # <- Add this line and run it at least once!

with open("SimpleStorage.sol", "r") as file:
    simple_storage_file = file.read()

compiled_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"simpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
            }
        },
    },
    solc_version="0.6.0",
)

print(compiled_sol)`

and my simpleStorage.sol is :

`//SPDX-License-Identifier: MIT
pragma solidity ^0.6.0;
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";
import "@chainlink/contracts/src/v0.6/vendor/SafeMathChainLink.sol";
contract FundMe {

    mapping(address => uint256) public addressToAmountFunded;

    function fund() public payable {
        uint min_USD = 50 * 10 ** 18;
        addressToAmountFunded[msg.sender] += msg.value;
    }

    function getVersion() public view returns (uint256) {
        AggregatorV3Interface priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);
        return priceFeed.version();
    }

    function getPrice() public view returns (uint256){
        AggregatorV3Interface priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);
        (, int256 answer, , ,) = priceFeed.latestRoundData();
        return uint(answer); //1,234.12345678
    }

    function getConversionRate(uint256 ethAmount) public view returns (uint256) {
        uint256 ethPrice = getPrice();
        uint256 ethAmount_USD = (ethPrice * ethAmount) / 1000000000;
        return ethAmount_USD;
    }

}`

Can anyone help to the solve the issue, thank you very much.

Hello @Oscar-Chung-CKL Is saying it could not find this: SafeMathChainLink.sol so I think it depends a lot on the version of chainlink you are using, could you please share your brownie-config.yaml?.

[Oscar-Chung-CKL]

in fact i am following the part using vs code instead of brownie, when i run deploy.py in vs code, this error occurs despite i have put the .sol and the .py in the same folder
Edit 1: (the part discussed at around 3:40:00 in the video https://www.youtube.com/watch?v=M576WGiDBdQ&t=13556s)
Edit 2: deploy.py works fine if i do not include : import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"; import "@chainlink/contracts/src/v0.6/vendor/SafeMathChainLink.sol";

Oh I see now, well in order to be able to import those @chainlink you should use a framework like brownie and configure them on a file called brownie-config.yaml which you are going to see later on the course, that's why you wasn't able to import them

[Oscar-Chung-CKL]

I see, thank you very much, then i think i will stop trying this on vs code and focus on the video first and try again when i see that in the video
Thank you very much for your help!

I'm glad it helped.
