Error: Cannot find module 'svelte/store.mjs'

After following the setup guide I get the error Error: Cannot find module 'svelte/store.mjs' when trying to run yarn dev

[mortscode]

Same issue

Respecting the yarn.lock file is the solution. Svelte and Sapper are out of sync otherwise.

@rob-balfre what do you mean by "respecting"? Can I just delete it and re-install the dependencies?

[rob-balfre]

@mortscode I had to use the lock file that is currently in this repo (don't delete or manually upgrade anything) and use yarn and not npm. The problem arose out of my Svelte and Sapper version being incompatible. From discord chat yesterday...

I'm guessing it's because you're getting Svelte >= 3.5.0 but aren't getting Sapper >= 0.27.3
https://github.com/sveltejs/sapper/blob/master/CHANGELOG.md#0273
There were internal changes in Svelte 3.5.0 that were supposed to not be very breaking, but they did require changes in Sapper
If you're installing with something other than Yarn, you won't be respecting their lock file, and the Svelte ^3.0.0 range would end up giving you too new of a version for the Sapper ^0.26 range

Also worth noting (not tried this yet)...

@rob_b I started with this firebase template as well, upgraded svelte to 361 and sapper to 0274 today and it works fine
fb version is 623
fb admin 820

Yeah, I saw those version updates and still struggling. I've been trying to make it work with NPM. I'll give yarn a go.

@mortscode good luck

Ok. I think I'm almost there. Strange issue where my assets aren't making their way down from firebase to my local. So I'm just getting the html with no assets or styles. Borat's jpg and global.css aren't in my static folder so I'm assuming it's not making its way down from the hosting server on firebase.

Any thoughts?

I'm getting this when I run firebase serve:
