Are you using npm or yarn?

If npm, can you run npm install --force?

[Jhoscy]

We have the same problem and I wanted to ask you why are using a "beta" as dependecy for Ethernal instead of the stable 2.0.5

[antoinedc]

Because of how Hardhat plugins work, Ethernal has to use the ethers version that is included in hardhat-deploy-ethers. The "beta" version is the version of hardhat-deploy-ethers, which uses and exports ethers v2.0.5.

I faced the same error and I fixed installing: "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13". If you are working using Linux (like me), you can get another error (not on MacOS) about keytar. In that case you need to run: sudo apt-get install libsecret-1-dev. Then, if you run npm i (with hardhat-ethernal 0.8.1), it works.

[Jhoscy]

On hardhat-ethernal 0.8.1 we are speaking with Antoine about changing in: hardhat-ethernal/dist/type-extensions.d.ts from

declare module "hardhat/types/config" {
    interface HardhatConfig {
        disableEthernal?: boolean;
    }
}

to

declare module "hardhat/types/config" {
    interface HardhatUserConfig {
        disableEthernal?: boolean;
    }
}

in order to not get static error in hardhat.config.js about disableEthernal

Sorry I'm not sure what is the fix you are mentioning here. Do you mind explaining?

At the moment, the only fix I'm aware of for the dependency issue is to either use yarn or the --force flag with npm.

[zeroarst]

I am having the same issue.. and I use --force and --legacy-peer-deps. It works fine. But if I want to install other deps, I got these error:

I need to uninstall hardhat-ethernal, install ohter deps, and try install hardhat-ethernal with --force or --legacy-peer-deps again...

[ludekvodicka]

Hi,

I have the same issue with 2.2.0 version of hardhat-ethers and 2.1.0 of hardhat-ethernals. Is there any solution for this, or it's necessary to use it together with --force flag only?

[antoinedc]

Hi,

Yes, at the moment, you have to use the --force flag to install it unfortunately.

[ludekvodicka]

thanks for the quick reply. Is there any eta for fixing this?

[antoinedc]

Not yet, last time I checked, this issue was still coming from a conflict due to how Hardhat handles plugins.

My assumption was that using the --force flag shouldn't be an issue in general. Is there a reason for you to not use it?

[ludekvodicka]

I think the issue is that hardhat already using beta.13 and your plugin beta.10. But maybe there is some other issue.

Regarding --force, the issue is that as soon as you use it once, you have to use it always, because it's not possible to call any other next "npm i " command without --force anymore.

[antoinedc]

I'll take a look at those versions.

I see. And have you tried using yarn instead of npm? I think it works without the force flag

[Metroxe]

I installed with npm install --legacy-peer-deps and got it to work. Probably not ideal, but should work until things are resolved.

[devrajsinghrawat]

This works for me

npm install --legacy-peer-deps hardhat-ethernal

[johngrimsey]

Hey, it's been a while on this one - possible to fix so force or legacy-peer-deps aren't needed? I see the config typings have made their way into Hardhat, perhaps that's relevant, not 100% sure.

Thanks for the ping! I started to work on it. Packages upgrade seem to be more complex than what I thought though

[antoinedc]

I've pushed a new version: 3.2.3 that should fix the issue. Please, let me know if that works

[johngrimsey]

Thanks @antoinedc will get back to you

Closing this for now, feel free to comment/reopen if the problem is still here.
