You must mention all peer dependencies in package.json

Guys, in your packages, for example in @v4-sdk, you import a lot of stuff from 'ethers/lib/utils', which is compatible with ethers v5 but not with v6.

But, since it's not presented in any of package.json files, your imports are referencing workspace's ethers version, which is in a lot of times v6.
So, this leads to build crashes with Package subpath './lib/utils' is not defined by "exports" error across the globe.

For the ones who's seeing it, this resolves the issue.

//package.json
{
  "pnpm": {
    "packageExtensions": {
      "@uniswap/v4-sdk@*": {
        "dependencies": {
          "ethers": "5.7.2",
        }
      }
    }
  },
  "overrides": {
    "@uniswap/v4-sdk@*": {
      "ethers": "5.7.2"
    }
  },
  "resolutions": {
    "@uniswap/v4-sdk/ethers": "5.7.2"
  }
}

It seem like no effect.

Please Uniswap team, could you use @ethersproject packages instead of importing ethers/lib/utils ? This issue has been hanging for almost a year now. I can take care of it is nobody has bandwidth. It is just a matter of removing ethers/lib/utils and replacing with the appropriate package.
