@sveltejs/kit is resolving modules from the wrong directory

[GrygrFlzr]

Describe the bug
kit is importing relative to its location in node_modules, not relative to the initialized project:

UnhandledPromiseRejectionWarning: Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'C:\Users\GrygrFlzr\Documents\projects\sk-35\node_modules\@sveltejs\kit\node_modules\@sveltejs\vite-plugin-svelte\' imported from C:\Users\GrygrFlzr\Documents\projects\sk-35\node_modules\@sveltejs\kit\dist\index2.js

Note \node_modules\@sveltejs\kit\node_modules\@sveltejs\vite-plugin-svelte\ instead of \node_modules\@sveltejs\vite-plugin-svelte\.

To Reproduce

# initialize a new project
# install vite to work around #412
$ npm run dev

> sk-35@0.0.1 dev C:\Users\GrygrFlzr\Documents\projects\sk-35
> svelte-kit dev

Expected behavior
Load dependencies from the correct directory

Information about your SvelteKit Installation:

  npmPackages:
    @sveltejs/kit: next => 1.0.0-next.35
    svelte: ^3.29.0 => 3.35.0

Severity
Completely unusable without monkey-patching @sveltejs/kit.

Additional context
In not-svelte-kit I fixed this issue by using import-meta-resolve, but I'm a bit more hesitant to add a new dependency to the official solution.

Workaround: Run npm run build inside node_modules\@sveltejs\kit\node_modules\@sveltejs\vite-plugin-svelte.

I think this is correct — vite-plugin-svelte is a dependency of Kit, not the project that uses it. I think the problem is that the vite-plugin-svelte package doesn't include the index.js, inexplicably. Fixed that in 8a9fcd6#diff-9b4d1e1724c3935da1984287277aace763e8a724298cb3b0c9db6d444d0d763a but now I'm struggling to convince npm to install that version in my project, I think because pnpm pins dependency versions when it publishes packages. Will cut a new Kit version to work around it

[GrygrFlzr]

Can confirm the version bump seems to have fixed this.
