Let's do some improvements to avoid npm/yarn/pnp problems with https://github.com/webpack/webpack-cli/blob/next/packages/serve/package.json#L17:

1. Remove webpack-dev-server from peerDependencies
2. "peerDependenciesMeta": { "webpack-dev-server": { "optional": true } }
3. Add

let webpackDevServer;

try { 
  webpackDevServer = require.resolve('webpack-dev-server') 
} catch (error) {
  throw new Error(`You need to install `webpack-dev-server` for running `webpack server`.\n${error}`);
}

Maybe we should improve error message, feel free to do it
