import NodeTypes from '@vue/compiler-core', NodeTypes is undefined

Describe the bug

import { describe, expect, it } from 'vitest';
import { NodeTypes } from '@vue/compiler-core';

describe('suite name', () => {
  it('import NodeTypes', () => {
   // TypeError: Cannot read properties of undefined (reading 'ATTRIBUTE')
    expect(NodeTypes.ATTRIBUTE).toMatchInlineSnapshot();
  });
});

why NodeTypes is undefined? I can't sure that is vite's reason.

NodeTypes is a const enum, it exists only in Typescript. It is compiled out of Vue, every instance is replaced with appropriate value. That is why you cannot import it.

And from Vite docs: https://vitejs.dev/guide/features.html#typescript

.. because esbuild only performs transpilation without type information, it doesn't support certain features like const enum and implicit type-only imports.
