npm i -D @sveltejs/kit@next Errors

[MrAmericanMike]

Sorry if this is not a problem with SvelteKit itself and maybe it's NPM fault. But I'm surprised to see this errors while installing a package.

Why it errors with complains that should show, if any, when running vite dev for example.

It also complained about config.kit.browser.hydrate has been removed.

Is this behavior normal?

No, this is the current behaviour: it is currently set up such that it won't install if it encounters some invalid configurations (for instance, this error in sveltekit.config.js. it similarly errors when trying to be installed to 'old-style' routing, which must be migrated before > next.405 versions will install. I'm not in a place to pass judgment on why this has been chosen.
