Describe the bug

Snowpack can't find dependency @npmcli/arborist.

Additional errors with NPM:

[11:21:00] [esinstall:@npmcli/arborist] /tmp/test/2/node_modules/@npmcli/arborist/lib/realpath.js
   Module "path" (Node.js built-in) is not available in the browser. Run Snowpack with --polyfill-node to fix.

Work perfectly with Snowpack version 3.7.1. But doesn't work on latest versions.

1. Create a new folder
2. Do pnpm add snowpack. Or npm install snowpack
3. Run npx snowpack dev
4. Errors!

Not specific to pnpm, happens with npm too.

EDIT: Latest npm works, only pnpm causes these errors.
