There was a breaking change introduced in Svelte sveltejs/svelte#5665

The fix is to update rollup-plugin-svelte to version 6.1.1

...
"rollup-plugin-svelte": "~6.1.1",

Couldn't create a fix branch on the repo, please update yourself.

Thanks for your help! I’m fixing the template

[Samuel-Martineau]

It should be fixed right now as all the tests pass. You should upgrade to [email protected].

Thanks for using generator-svelte!

FYI I didn't run into this with Node 10.x (10.23, specifically), but just upgraded to Node 12.x (12.20.0) then suddenly did.

[Samuel-Martineau]

But does it work now with node 12?

[elimisteve]

Yes, the above fix worked (upgrading to 6.1.1), I'm just adding that I didn't get the "Package subpath" error at all when using Node 10.

Goddamn. The whole ecosystem is rigged, rigged and should follow Windows Philosophy of backwards compatibility.

It's been a year since I wrote my app and it already broken.

WTF with X-Gen!!!!!
