Lesson 7 : Error "Call the contract method without broadcasting a transaction."

Can you help me with this error?
#302

Hi irwing I wonder why are you importing the contracts from node_modules instead of @chainlink?

regarding to the Virtual machine error it seams is has to be with your getEntranceFee function, could you please paste your deploy and test scripts here?

Sure, this is my repo:
https://github.com/irwingtello/lottery

And my error:
Compiling contracts... Solc version: 0.8.9 Optimizer: Enabled Runs: 200 EVM Version: Istanbul CompilerError: solc returned the following errors:

ParserError: Source "C:/Users/irwin/.brownie/packages/smartcontractkit/chainlink-brownie-contracts@1.1.1/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol" not found: File not found. --> contracts/Lottery.sol:4:1: | 4 | import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Hello Irwing the error is the following your are importing the AggregatorV3Interface in version 0.8 and on your brownie-config.yamlyou are using the dependency on version 1.1.1:

 dependencies:
  - smartcontractkit/chainlink-brownie-contracts@1.1.1
compiler:
  solc:
    remappings:
      - '@chainlink=smartcontractkit/chainlink-brownie-contracts@1.1.1'

If you check the github of chainlink-brownie-contracts version 1.1.1 you will notice there is not a version 0.8:

https://github.com/smartcontractkit/chainlink-brownie-contracts/tree/1.1.1

So the solution is, to change the version you are importing from 1.1.1 to 0.2.2 and this should work.
