I've seen several other packages that doesn't work with pnpm too before.

So, what's the reason cause such issue, is it pnpm or specific packages (e.g hardhat) responsible for such issue?

I really prefer to use pnpm, because it's much quicker than npm.

Answer 1

Try the command:

pnpm config set auto-install-peers true

After that, just repeat your command and it will automatically install all the dependencies.
