Error while creating 'Library skeleton project'

[stuymedova]

Describe the bug

I have just started a new project using the npm create svelte@latest command. After which I chose the following options:

✔ Where should we create your project?
  (leave blank to use current directory) … 
✔ Which Svelte app template? › Library skeleton project
✔ Add type checking with TypeScript? › No
✔ Add ESLint for code linting? … No / Yes
✔ Add Prettier for code formatting? … No / Yes
✔ Add Playwright for browser testing? … No / Yes

Then run npm install and upon completion npm run build. I received the following error:

> Failed to locate tsconfig or jsconfig

Reproduction

I suppose that instructions above would be sufficient because I've started from scratch.

A jsconfig or tsconfig is required for @sveltejs/package unless you turn off the emit types option, and since you added "no", it throws an error because no such config could be found while trying to generate type definitions from your Svelte file.
This works as designed, but the error could be better in explaining why you need one.
