Runtime error with rollup

I am trying to use ethers for a browser-based app, built with rollup.

Package in package.json is:

  "dependencies": {
    "ethers": "^5.1.0",
    ...

The sample code from the doc:

  import { ethers } from "ethers";
  if (window["ethereum"] !== undefined) {
    const provider = new ethers.providers.Web3Provider(window["ethereum"]);
    const signer = provider.getSigner();
  } else {
    alert("no wallet");
  }

builds properly but gives a runtime error in browser console:

Uncaught (in promise) TypeError: Failed to resolve module specifier "util". Relative references must start with either "/", "./", or "../".

It seems that some Node-related bits are included in the build, despite having in rollup.config.js:

resolve({
      browser: true
})

All resolved with new separate imports from 5.6

Thanks again for making this great lib!

you are right dude, but in my opinion they should fix that issue and also give an explanation why the import { ethers } from ‘ethers’ doesn’t work, in my case I got an << Uncaught TypeError: Error resolving module specifier “ethers”. Relative module specifiers must start with “./”, “…/” or “/”. >> when using the import I previously mentioned, but then importing the cdn everything works fine.
