Failed to deploy ReverseRegistrar contract

[phenix3443]

When I followed the deploying-ens-on-a-private-chain to deploy the contract via hardhat I encountered the following error：

$ npx hardhat run scripts/deploy.js

HardhatError: HH700: Artifact for contract "ReverseRegistrar" not found.

Is there a problem somewhere? Very much feel your answer.

I needed this to in the dependencies:

import {ENSRegistry} from "@ensdomains/ens-contracts/contracts/registry/ENSRegistry.sol";
import {PublicResolver} from "@ensdomains/ens-contracts/contracts/resolvers/PublicResolver.sol";
import {FIFSRegistrar} from "@ensdomains/ens-contracts/contracts/registry/FIFSRegistrar.sol";
import {ReverseRegistrar} from "@ensdomains/ens-contracts/contracts/reverseRegistrar/ReverseRegistrar.sol";

Note the last line, it forget to add it to the docs
