Lesson 7: ChainLink Library not found.

[ashrth]

Hello guys, I am stuck on lesson 7 (10:44:06) the error I am facing is after compiling the MockV3Aggregator.sol

Error HH411: The library @chainLink/contracts, imported from contracts/test/MockV3Aggregator.sol, is not installed. Try installing it using npm.

The error is easy to resolve I guess, But I am unable to find the right code for installing this library.
I'd appreciate your help.

Also, I am running the newer version of hardhat so a lot of files are missing from my directory as well, do you think this is the reason, it is throwing this reason?

In package.json, add this (in devDependencies)

"@chainlink/contracts": "^0.4.1",

Then, do yarn install. Running yarn hardhat compile should work now.

No, I corrected this later, still the same. I will try to remove the dependency and add it again.

Rather install everything in one go for conflicts.

• yarn hardhat clean
• Delete node_modules
• yarn install
• yarn hardhat compile

Alrighty, thanks mate
