SDK Setup

Using a fresh install of a Sveltekit project, one can not install the sentry sdk.

This are the current dependencies with a clean project:

"devDependencies": {
	"@sveltejs/adapter-auto": "^3.0.0",
	"@sveltejs/kit": "^2.0.0",
	"@sveltejs/vite-plugin-svelte": "^3.0.0",
	"@types/eslint": "8.56.0",
	"@typescript-eslint/eslint-plugin": "^6.0.0",
	"@typescript-eslint/parser": "^6.0.0",
	"eslint": "^8.56.0",
	"eslint-config-prettier": "^9.1.0",
	"eslint-plugin-svelte": "^2.35.1",
	"prettier": "^3.1.1",
	"prettier-plugin-svelte": "^3.1.2",
	"svelte": "^4.2.7",
	"svelte-check": "^3.6.0",
	"tslib": "^2.4.1",
	"typescript": "^5.0.0",
	"vite": "^5.0.3",
	"vitest": "^1.2.0"
}

Steps to Reproduce

Start with a fresh directory

• npm init vite
• Select
  • Svelte
  • SvelteKit
  • Skeleton Project
  • Yes, using Typescript syntax
  • Pick everything except Try the Svelte 5 preview
• Wait for the project to be created
• Run npm install --save @sentry/sveltekit

Expected Result

Correct installation

Actual Result

# npm resolution error report

Fix the upstream dependency conflict, or retry
this command with --force or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.

Hi @Bullrich thanks for writing in!

I tried to follow your exact reproduction steps and couldn't reproduce the issue. I created this repo with the results of my reproduction attempt. Please let me know if there's any difference or how I can reproduce the issue on my end. Thank you!

Worth noting, our SvelteKit SDK only requires "@sveltejs/kit": "1.x || 2.x" as a peer dependency so I don' see the potential for conflict here. Any chance another dependency is interfering here?

[Bullrich]

Confirmed! Thanks @Lms24 for looking into it.

I think it was a problem with my package manager.

After deleting node_modules and updating to use node 20 it worked without any problems.
