sveltejs
The requested module '__' does not provide an export named '__'
Describe the bug
Ever since updating to the latest SvelteKit my project has had nothing but random error after random error. Sometimes a "SemiColon missing" or "export not provided" or you name it. A meaningless change such as adding a space, removing the space, and rebuilding makes it work -- until I make any changes again, then a new random error shows.
So I decided to just start over from scratch with a fresh folder, new create svelte@latest my-app -- but the issue came up here too. I installed adapter-static npm i -D @sveltejs/adapter-static and npm run build works fine. But when I start the preview server, I get the following:
error when starting preview server:
file:///~/svelte.config.js?ts=1670677968927:1
import adapter from '@sveltejs/adapter-static';
^^^^^^^
SyntaxError: The requested module '@sveltejs/adapter-static' does not provide an export named 'default'
at ModuleJob._instantiate (node:internal/modules/esm/module_job:124:21)
at async ModuleJob.run (node:internal/modules/esm/module_job:190:5)
Note: while this fresh project shows The requested module '@sveltejs/adapter-static' does not provide an export named 'default' - in my original project this would be random. One time it might be adapter-static, but the next it might be The requested module './endpoint.js' does not provide an export named 'is_endpoint_request'
Reproduction
To reproduce:
- Run
create svelte@latest my-appto install SvelteKit (skeleton, TypeScript, no lint, prettier, no Playwright) - Run
npm i -D @sveltejs/adapter-staticfor Adapter Static - Update svelte.config to use adapter static
adapter: adapter({ pages: 'build', assets: 'build', fallback: 'app.html', precompress: true })(the defaults) - Run
npm run buildthennpm run preview

Additional Information
I originally brought this up in Discord: https://discord.com/channels/457912077277855764/1050686836370055218, brought it here when it happened on a fresh setup.
This is preventing me from working on an update to my app that I am supposed to launch in 5 days to my customers. 🥹
I hope it's an easy fix, I am frazzled... no idea what else to try.
Thank you.

IOW identical package versions, and I installed Node 19.1.0 to verify that wasn't the issue.
Honestly, this doesn't sound like a SvelteKit issue, it sounds like your Node installation is fucked somehow and it's failing to resolve modules. Are you seeing anything similar with other projects?
Ah, I don't have any other projects currently... packed those away some time ago.
But I wouldn't put it past Node being the culprit. Could be a coincidence that it started after an npm update to get the latest SvelteKit.
Interestingly, the errors have gone away "-ish." 😀 By that I mean every once in a while it pops up, but not every time. I can work again, but I feel like I'm coding on eggshells (as if to be extra safe or something lol).
Probably unrelated, but I had to comment out vitePreprocess() in new svelte.config because I was getting Sourcemap for "/~/src/lib/components/COMPONENTNAME.svelte" points to missing source files for every component (below works fine).
preprocess({
postcss: true
})
Bringing it up in case it gives any clues.
Thank you for the reply Rich, I appreciate it. 🙏
Closing as the original issue has been resolved and we can't reproduce it.
