Openzeppelin Files Not Found in chainlink-brownie-contracts

[vicjuma]

I am receiving a dependency for chainlink-brownie-contracts where some files for openzeppelin cannot be found. Here are the errors that are detected in Visual Studio Code problems tab. The file that is affected is KeeperRegistryBase1_3.sol

Source "@openzeppelin/contracts/security/Pausable.sol" not found: File outside of allowed directories.
Source "@openzeppelin/contracts/security/ReentrancyGuard.sol" not found: File outside of allowed directories.
Source "@openzeppelin/contracts/utils/structs/EnumerableSet.sol" not found: File outside of allowed directories.

I think this is why I am receiving an error server returned an error response: error code 3: execution reverted, data: "0x" on calling the FundMe getVersion function from Chainlink data feeds with cast call. Here is my code

function getV() public view returns (uint256) {
        address chainlinkAddress = 0x694AA1769357215DE4FAC081bf1f309aDC325306;
        return AggregatorV3Interface(chainlinkAddress).version();
    }

I am using chainlink-brownie-contracts version 1.3.0, my cast version is 0.2.0. Kindly help. Thanks.

You need to install Openzeppelin lib, you cannot find ReentrancyGuard and all in the chainlink-brownie lib,
please use this command in your terminal
forge install openzeppelin/openzeppelin-contracts --no-commit

Thank you, the error is gone but now my cast call returns 0x.

function getV() public view returns (uint256) {
        address chainlinkAddress = 0x694AA1769357215DE4FAC081bf1f309aDC325306;
        return AggregatorV3Interface(chainlinkAddress).version();
    }

Actually, function getV() function is not returning any value this is due to may be the contract did not deployed till now!! May be can you check whether did you deploy the contract or not ?

Hello @vicjuma, There is no chainlink price-feed contract on the Anvil Blockchain. I will advise that you follow Patrick as he teaches you, and later on, he will teach you how to fork a blockchain to run a test and how to test stuff locally by creating a Mock.

Hello @EngrPips , it is now that I understand that. Let me follow through. I got ahead of myself. Thanks muuch. Thanks too @heheboii11 . I am new to web3 bytheway and it is so amazing the milestones I have moved by following Patrick's tutorials and the Cyfrin community in general. Thank you all.
