Error reported at impot function：
"@chainlink/contracts/src/v0.8/VRFConsumerBaseV2.sol" not found: File not found. Searched the following locations: "".solidity(6275)

I'm pretty sure "@chainlink/contracts/src/v0.8/VRFConsumerBaseV2.sol" exists:

No errors reported in"yarn hardhat compile":

I'm confused is this correct?

hi, it's because of your solidity extension in your vs code, you can ignore that it's bug somtimes happens.
important thing is you can compile it successfully

I get a similar error:

"C:/Users/User/.brownie/packages/smartcontractkit/chainlink-brownie-contracts@0.6.1/contracts/src/v0.8/vrf/VRFConsumerBaseV2.sol" not found: File not found. Searched the following locations: "".
--> contracts/VRFV2Wrapper.sol:15:1:

Mine does not compile. Does this have something to do with the dependency '0.6.1'? I also note that the end of my error code is a bit different from MrPointSun's. The file I am attempting to compile is VRFV2Wrapper.sol. And I am doing so with the line,

import "@chainlink/contracts/src/v0.8/vrf/VRFConsumerBaseV2.sol";

@wwignes88 Please leave your repo so I can see your code.

my repo: https://github.com/wwignes88/Chainlink-Question

I am trying to follow the [chainlink] steps on testing by deploying mocks here which is the direct funding method. I've yet to try to the subscription method. I am just using testnets.

see lines 4-6 of the VRFV2Wrapper.sol file in rhe repo. Line 6

import "@chainlink/contracts/src/v0.8/vrf/VRFConsumerBaseV2.sol";

when attempting to run 'brownie compile' produces the error,

  'File not found.  Searched the following locations: --> contracts/VRFV2Wrapper.sol:4:1:'

all other imported .sol contracts seem to compile fine. Thanks.

OKAY. I think I get it now. Haven't tested the solution thoroughly yet but so far it seems to work and more than that it makes sense to me.

A) One mistake I likely made is I installed openzeppelin directly instead of relying on the chainlink download of this repo. If open zeppelin is downloaded, e.g.,

npm install @openzeppelin/contracts

prior to running

npm install @chainlink/contracts --save

then you are likely to get something like,

2 high severity vulnerabilities

after the download and probably it won't compile. Upon reading the chainlink README file contained in the node_modules folder they warn this package is designed to be self-contained [paraphrase].

B) I was pulling a beginners mistake and was looking at the github repo instead of the files actually contained in node_modules folder to find the file path!

C) I had to add 'node_modules/' to the beginning of the import path. This is strangely out of line with anything I've found online, but makes sense according to my experience with python. So we'd have

 import node_modules/@Chainlink/contracts/....
