Dynamic import vars fail in dev

⚠️ IMPORTANT ⚠️ Please check the following list before proceeding. If you ignore this issue template, your issue will be directly closed.

[x] Read the docs.
[x] Use Vite >=2.0. (1.x is no longer supported)
[x] If the issue is related to 1.x -> 2.0 upgrade, read the Migration Guide first.

Describe the bug

Dynamic imports with variables have been working in Vite 1. In the latest version of Vite 2 errors are thrown in development mode — Vite seems unable to find the related file, although path's are correct. Building the app works fine.

The following code generates the routes:

const routes = [
  ...site.children.map(page => ({
    path: `/${page.uri}`,
    component: () => import(`../views/${capitalize(page.template)}.vue`).catch(() => Default)
  }))
]

Vite displays error messages like:

Failed to load url /views/Home.vue (resolved id: /views/Home.vue). Does the file exist?

Regular imports work just fine:

import Default from '../views/Default.vue'

I think some suffix is missing. Vite calls /views/Home.vue?import and cuts off everything after "import". It probably should look similar to /src/views/Default.vue?vue&type=style&index=0&scoped=true&lang.css.

Thanks in advance for taking a look!

Describe the bug

Relative library import still doesn't work for me

 [vite] Internal server error: Failed to resolve import ".entry.js". Does the file exist?
  Plugin: vite:import-analysis
  File: /Users/maks/Projects/revo-vite/vite-project/node_modules/.vite/@revolist_revogrid_loader.js?v=d36e8090
  1519|      return o[r];
  1520|    }
  1521|    return import("./" + a + ".entry.js").then(function(e2)

The library has relative reference which vite can't read.
