Hey @LDJ, check this discussion on github: github.com/smartcontractkit/full-blockchain-solidity-course-py/… Its relationed about this repo from NPM packages: github.com/smartcontractkit/chainlink-brownie-contracts "As of 1.2.0 and onward all the releases of this package are going to match the @chainlink/contracts NPM tags So it will look "backwards", but we are starting with 0.2.1" – Letrice

"As of 1.2.0 and onward all the releases of this package are going to match the @chainlink/contracts NPM tags So it will look backwards, but we are starting with 0.2.1"

Answer 5

More elegant solution.

1.yarn add @chainlink/contracts
yarn add @openzeppelin/contracts #I use it for the SafeMath

2. import"node_modules/@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"; import"node_modules/@openzeppelin/contracts/utils/math/SafeMath.sol";

Answer 6

The import can beimport "@chainlink/contracts/src/v0.8/shared/interfaces/AggregatorV3Interface.sol";

instead of import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"
