bun run check fails with "Type 'Promise<Plugin_2[]>' is not assignable to type 'PluginOption'."

[codinkai]

Describe the bug

Hi,
I have setup a new sveltekit project with typescript and prettier enabled.

When I run bun run check, I get the error below.

What can I do to get rid of this error?

Reproduction

npm create svelte@latest my-app
cd my-app
npm install
npm run check

npm create svelte@latest my-app
cd my-app
npm install
npm run check

I can't reproduce the issue with these instructions. Please provide a proper minimal reproduction in the form of a downloadable repository.

[codinkai]

I am so sorry. My instructions were wrong. I have tested out bun for this example. As I thought it is a "drop-in" replacement for node, I assumed the instructions should be same. But I cannot reproduce it with node as well.

curl -fsSL https://bun.sh/install | bash
bun create svelte@latest my-app
cd my-app
bun install
bun run check

When creating the app I selected the following options:

bun create svelte@latest my-app-3

create-svelte version 5.1.0

[Conduitry]

Issues that arise only with Bun are not something we can afford to try help debug. Bun may have reached 1.0, but a lot of it is still very likely to be unstable or not working yet. If it's operating in a mode that says it's a drop-in replacement and it's behaving differently than Node, that sounds like an issue on Bun's end.

The issue is resolved. Does not occur in bun version 1.0.6 anymore.

Also, see oven-sh/bun#5677.

[AlbertMarashi]

Hmm I still seem to be getting it even on the latest version of bun

[AlbertMarashi]

import { sveltekit } from "@sveltejs/kit/vite"
import { defineConfig } from "vitest/config"
import arraybuffer from "vite-plugin-arraybuffer"

export default defineConfig({
    plugins: [
        sveltekit(),
        // used for importing fonts in satori /api/og/+server.ts
        arraybuffer(),
    ],
    test: {
        include: ["src/**/*.{test,spec}.{js,ts}"],
    }
})

This is specifically happening when I use the vitest/config

[dually8]

I'm getting the same error in a brand new sveltekit project using the sv cli.

If bundling, conditions should include development or production. If not bundling, conditions or NODE_ENV should include development or production. See https://www.npmjs.com/package/esm-env for tips on setting conditions in popular bundlers and runtimes.
