`vite build` errors on brand new vite app

This is probably a user error since I've never used rollup before. On a brand new vite app created with create-vite-app vvv I am able to run the app with npx vite and browse to localhost just fine. Running npx vite build however throws an error:

~/Src/vvv$ npx vite build
vite v0.10.3
Building for production...
[vite] Build errored out.

I do see the Note that you need plugins to import files that are not JavaScript warning, and the error seems to suggest that it's trying to parse index.html line 1 column 0.

What sort of things do I have to do to make this work? Should vite build be trying to rollup index.html? Do I need to install the @rollup/plugin-html package?

npm run build

That gives the same error.

We probably need to add Windows CI at some point, most likely a Windows path related problem.

Should be fixed in 0.11.4.

@yyx990803 This is still broken in v0.14.1 Build errored out with PARSE_ERROR on index.html, line 1 pos 0, which is now the <!DOCTYPE html> tag.

All CI is passing so nothing can be done without a reproduction.

I'm having the same error too and it is related to case missmatch with windows drive letters in rollup. The problem is with load function in htmlPlugin:

const htmlPlugin: Plugin = {
    name: 'vite:html',
    async load(id) {
      if (id === indexPath) { // fails if windows drive letter case missmatch
        return js
      }
    },
    ...
  }

If I change this to if (id.toLowerCase() === indexPath.toLowerCase()) or something like this (widows path's are case insensitive), it works as expected.

@dariuski looks like you are using an outdated version. There's no longer such code in the latest release.
