Vite 3 - npm package as `rollupOptions.input` fails when package is unused by other inputs

[bholmesdev]

Describe the bug

I am running a Vite 3 production build via the JavaScript API, and I'm using an npm package within my build.rollupOptions.input array. This succeeds for npm packages used by other files in the input array. However, if that npm package is unused by other inputs, the build will fail!

Example:

import { build } from 'vite';
(async () => {
  await build({
    build: {
      rollupOptions: {
        input: [
          // Fails when resolving the npm package alone
          'is-odd',
          // ...but succeeds if that npm package is used by another input.
          // Uncomment this line to fix the error 👇
          //'src/test-module.js',
        ],
      },
    },
  });
})();

Interestingly, I was unable to replicate in Stackblitz. See the link below for a step-by-step reproduction when running locally!
