'getContract' function does not exist on HardhatRuntimeEnvironment.ethers

[naddison36]

I've installed the hardhat-deploy-ethers extension into my TyoeScript project and imported it in my hardhat.config.ts file

import "hardhat-deploy-ethers"

When I try and use the getContract function in a deploy script like the following

import { DeployFunction } from "hardhat-deploy/dist/types"
import { HardhatRuntimeEnvironment } from "hardhat/types"
import { CurvedMasset } from "types/generated"

const func: DeployFunction = async (hre: HardhatRuntimeEnvironment) => {
    const mBTC = (await hre.ethers.getContract("mBTC")) as CurvedMasset
}

I get the following TypeScript error

Property 'getContract' does not exist on type '{ provider: JsonRpcProvider; getContractFactory: { (name: string, signerOrOptions?: Signer | FactoryOptions): Promise<ContractFactory>; (abi: any[], bytecode: BytesLike, signer?: Signer): Promise<...>; (name: string, signerOrOptions?: string | ... 1 more ... | FactoryOptions): Promise<...>; (abi: any[], bytecode: By...'. Did you mean 'getContractAt'?ts(2551)

If I put in a // @ts-ignore before the line with the getContract function, the deploy scripts work fine.

My tsconfig.ts file looks like

{
  "compilerOptions": {
    "outDir": "./transpiled/",
    "sourceMap": true,
    "noImplicitAny": false,

Could it be that you also use a plugin that depends on @nomiclabs/hardhat-ethers ?

If so, you ll need to alias @nomiclabs/hardhat-ethers to hardhat-ethers-deploy This might not solve the typing issue, but worth a try

With npm : npm i -D @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers

Recently hardhat team made @nomiclabs/hardhat-ethers itself extensible so my plan is to update hardhat-deploy-ethers to extend it instead of being a fork of it. No timeline yet though.

Thanks, @wighawag. Using the above alias worked

It didn't fully work for me though... yarn add @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers

warning Pattern ["@nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers"] is trying to unpack in the same destination "/home/manu/.cache/yarn/v6/npm-@nomiclabs-hardhat-ethers-0.3.0-beta.7-860d86b84ed3c4fdef64283ccf1e8d5623454d02-integrity/node_modules/@nomiclabs/hardhat-ethers" as pattern ["hardhat-deploy-ethers@^0.3.0-beta.7"]. This could result in non-deterministic behavior, skipping. ... warning " > @nomiclabs/hardhat-waffle@2.0.1" has incorrect peer dependency "@nomiclabs/hardhat-ethers@^2.0.0".

yarn upgrade-interactive

error Couldn't find any versions for "@nomiclabs/hardhat-ethers" that matches "^0.3.0-beta.7"

package.json

{
  "dependencies": {
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",
    "hardhat": "^2.1.2",
    "hardhat-deploy": "^0.7.0-beta.56",
    "hardhat-deploy-ethers": "^0.3.0-beta.7"
  }
}

Any ideas?

[wighawag]

you need to remove that line "hardhat-deploy-ethers": "^0.3.0-beta.7"

and then you need to import @nomiclabs/hardhat-ethers in your hardhat.config.js instead of hardhat-deploy-ethers. I need to add that to the doc actually.

For people experiencing this issue in the future, you can implement this workaround instead of using ethers.getContract(), and it should be the same.

 await deployments.fixture(["MyContract"]);

 const myContract = await deployments.get("MyContract");

 const contract = await ethers.getContractAt(
      myContract.abi,
      myContract.address
    );
  });

Thanks rodrigoherrerai, this worked perfectly.

This:

With npm : npm i -D @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers

With this:

yarn upgrade-interactive

Fixed it for me in 2 repos already 🙏🏻

[usman571]

npm i -D @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers

   deployer = (await getNamedAccounts()).deployer;
    await deployments.fixture(["all"]);
    console.log('deployer',deployer)
    // fundMe = await ethers.getContract("FundMe", deployer);
     const contract = await deployments.get("FundMe");

  fundMe = await ethers.getContractAt(
      contract.abi,
      contract.address
    );
  });

how to apply the deployer though
