Optimized dependency error

Do NOT ignore this template or your issue will have a very high chance to be closed without comment.

Describe the bug

When I added ant-design-vue, an error occurred.

Dep optimization failed with error:
[vite]: Rollup failed to resolve import "indexof" from "indexof?commonjs-external".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`rollupInputOptions.external`
(node:28953) UnhandledPromiseRejectionWarning: Error: [vite]: Rollup failed to resolve import "indexof" from "indexof?commonjs-external".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`rollupInputOptions.external`

I tried adding indexof to rollupInputOptions.external, but this did not work.

At the same time, the project has another error.

import Ant from 'ant-design-vue';

import 'ant-design-vue/dist/antd.css'

When the following two sentences are introduced at the same time, vite will prompt to add ant-design-vue/dist/antd.css to optimizeDeps.include. But after I added it, an error was reported, and the error message is as follows

Dep optimization failed with error:
Entry module cannot be external (node_modules/ant-design-vue/dist/antd.css).

@yyx990803 60a4708 好像只是把报错改成了报警，真正导致错误的原因似乎是 ant-design-vue 引用了 indexof 而 rollup 处理失败了

Hi @anncwb

I just ran into this problem too. I fixed it (surprisingly) by adding a leading slash to the file path.

e.g. change import 'ant-design-vue/dist/antd.css' to

import '/ant-design-vue/dist/antd.css'

Hopefully, it will help you.
