Svelte 4 build now fails due to dependency issues: Seems to depend on svelte@"^5.0.0-next.96 || ^5.0.0"

[asimons04]

Describe the bug

My Svelte4 project is now failing to build because it cannot resolve the dependency svelte@"^5.0.0-next.96 || ^5.0.0" from @sveltejs/vite-plugin-svelte@4.0.0.

I always clear my node nodules/cache before doing a release build, and after that, the build started to fail. I last cleared my cache ~2 days ago, and no changes to my dependencies have been made since.

The only node packages in the chain that had dependency failures and recent pushes are svelte and vite-plugin-svelte. svektejs/kit was last updated 5 days ago, but I'm using an older version.

Relevant package.json:

"devDependencies": {
    "@sveltejs/adapter-node": "^2.1.0",
    "@sveltejs/kit": "^2.5.18",
    "@vite-pwa/sveltekit": "^0.3.0",
    "svelte": "^4.2.18",
    "svelte-check": "^3.8.4",
    "svelte-gestures": "^4.0.0",
    "svelte-hero-icons": "^5.1.0",
    "tslib": "^2.6.3",
    "typescript": "^5.5.2",
    "vite": "^5.0.0",
    "vite-plugin-pwa": "^0.20.0",
    "vitest": "^1.6.0"
  },

Reproduction URL

Reproduction

1) Open a new terminal and run npm install 2) See dependency errors that were not errors two days ago (and no changes to package.json dependencies)

https://kit.svelte.dev/docs/migrating-to-sveltekit-2#updated-dependency-requirements SvelteKit v2 has vite-plugin-svelte as a peer dependency. You should include v-p-s as a devdep in your package.json, rather than letting it be implicitly installed. This lets you control which version of v-p-s you have installed, so you don't upgrade to a version that requires Svelte 5 until you're ready to do that upgrade.

Yep, sure does. Thanks for pointing that out. It's funny this got me because I hate relying on implicit behavior. Can't believe I missed that.
