Try running the installation command with the --force flag:

npm install --save-dev --force @nomiclabs/hardhat-waffle 'ethereum-waffle@^3.0.0' @nomiclabs/hardhat-ethers 'ethers@^5.0.0'

Try stopping the server before making the installation.

Ctrl + c

Maakai123 commented 2 years ago

Avelous commented 2 years ago

I experienced these kind of issues before when installing dependencies so i alway clear cache and it works for me

npm cache clean --force

snake-py commented 2 years ago

Is there no better way than forcing the dependencies? @Salvien-code ?

ximon-x commented 2 years ago

@snake-py, there's probably going to be a better alternative but I don't know it since I don't know the root cause.

I'm on Linux so I can't reproduce the bug which might be a windows issue.

Hence, it's best to just use the --force flag until someone else provides a better alternative.

snake-py commented 2 years ago

@Salvien-code I am on Ubuntu 20 and I am seeing the same dependency conflict. When did you try out the installation the last time? Maybe some dependency got updated and they forgot to increase the version on a co-dependency?

I installed them months back, but I couldn't reproduce the bug back then.

Can you please send the command you ran and also the log of your error message?

I am running Node 16.16.0 and npm 8.19.2 via nvm

ximon-x commented 2 years ago

@snake-py It's quite odd but I got similar error message when I ran the command, but it worked when I used yarn:

yarn add -D @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers @nomiclabs/hardhat-etherscan @nomiclabs/hardhat-waffle chai ethereum-waffle hardhat hardhat-contract-sizer hardhat-deploy hardhat-gas-reporter prettier prettier-plugin-solidity solhint solidity-coverage dotenv

Although there were a ton of warnings from yarn, the installation was successful. This also explains why I didn't encounter the error in the past. I've always used yarn for installing node modules and rarely ever use npm.

So this is most likely an npm issue.
