HeritagePalms · 2021-09-07T20:38:19Z

I get the same thing once I upgraded to sveltekit 1.0.0-next.164. The two packages for me though are:
sveltejs/adapter-vercel
sveltejs/kit

GageBachik · 2021-09-07T23:18:54Z

Bump. Same error upon even making a brand new repo.

Simply running:

npm init svelte@next test cd test npm run dev

produces:

Vite had already made another release (2.5.6), what's left is to upgrade Vite

benmccann · 2021-09-08T17:30:50Z

I cut a release with a new version of Vite

In case this helps anyone, I ran into the same problem after replacing all occurrences of import type { ... } with import { ... }.

TypeScript users no longer have to strictly separate type imports and value imports (...)
- Svelte October blog post

It seems that some imports, such as those importing from @svelte/kit or those in <script context="module"> still need explicit type imports (I'm not sure which is the cause). Another solution is to use JS and a @type hint such as in the Svelte docs.

<script context="module" lang="ts">
  import type { Load } from "@sveltejs/kit";
  export const load: Load = async ({ page, fetch }) => {

<script context="module">
  /**
   * @type {import("@svelte/kit").Load}
   */
  export async function load({ page, fetch }) {

dummdidumm · 2021-10-04T16:28:00Z

If the import consists of type imports only, you need to use import type

rburgst · 2022-07-13T07:06:00Z

If the import consists of type imports only, you need to use import type

Thanks for the hint, but then why doesnt sveltekit produce a meaningful error message? This is cropping up again and again and it always takes a while until you figure out where its wrong.

dummdidumm · 2022-07-13T07:42:53Z

@bluwy I suspect this error is thrown by either vite or vps - is there a way to throw a different error there, something like "X is not a valid import from Y. If this is a type import, use the import type syntax." or sth like that?

bluwy · 2022-07-13T09:14:02Z

From the errors, looks like it's coming from Vite's dep scanner, which uses esbuild to process TS, and it tries to resolve @sveltejs/kit because it's not a type import. I guess we can add an extra heuristic where if it fails to resolve, it checks if there's a type condition and suggest that. But it would be a fair refactor before we can do that. I'll put this in my todo list 🙂

rolandm2017 · 2023-02-20T18:56:59Z

Does this have a fix yet? I get the same or a similar bug when I add import { error } from "@sveltejs/kit" to a svelte component

the bug states:

[vite] Internal server error: Failed to resolve entry for package "@sveltejs/kit". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." entry in "@sveltejs/kit" package

bluwy · 2023-04-08T07:54:01Z

I can't reproduce this anymore. The errors come around when you require('@sveltejs/kit'), because SvelteKit only exports with the import condition, not the require condition. This can happen when some tooling compiles the import you write, into a require, and sometimes that can happen because the package.json "type": "module" not set, maybe that's the case?
