Error when installing Cheerio.js

[Lucho Zeraus]

I'm trying to use Cheerio on my React app, and after installing the package, when I run yarn start I get:

error Command failed with exit code 1.

this is my snowpack.config.json. I added the rollup-plugin-node-polyfills but I probably did it wrong, any idea how to fix that?

[Fred K. Schott]

This is a documentation issue that we need to resolve, where we currently support two different types of plugins: Snowpack plugins & Rollup Install plugins. Your config should instead be:

"installOptions": {
  "rollup": {
    "plugins": ["rollup-plugin-node-polyfills"]
  }
}

And then you can remove that plugin from the top-level plugins config.
