hardhat-deploy-ethers not compatible with hardhat-toolbox when using npm

[jiaochangyang]

Hi,

I am unable to install hardhat-deploy-ethers when I have hardhat-toolbox in my dependencies. My package.json dependencies look like:

"devDependencies": {
        "@nomicfoundation/hardhat-toolbox": "^1.0.2",
        "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13",
        "ethers": "^5.5.4",
        "hardhat": "^2.10.1",
        "hardhat-deploy": "^0.11.11"
}

I've tested with npm v.8.11.0 (which is bundled with Node 16LTS) as well as the latest v8.15.0. The error received is:

I could technically fix it by forcing the dependencies or using legacy-peer-deps but thought it might be good to raise this issue.

@wighawag i guess that's the same issue i also have with #28

[wighawag]

@wottpal yes most likely, The blocker is on hardhat repo : NomicFoundation/hardhat#1040

[wottpal]

Ok, but definitely thanks for the quick follow-up here. It's nice to know that you are on it :)

Hi! Is there any workaround while the 1040 issue is fixed?

[wottpal]

@wighawag any updates on this? can we help?

[wighawag]

Hey @wottpal Franco has made a PR to finally fix the issue but I did not get yet the time to look at it : #30

[wottpal]

Really nice. Had a look, but unfortunately it's really only the function interfaces that seem to be in the PR yet.

hardhat-deploy-ethers@next has been released
Please, try it out.

It is now an extension to hardhat-ethers so you need both

But note that that new version do not support external artifact if you were using them
