[@vue/compiler-sfc] <script setup> is still an experimental proposal.
Follow its status at vuejs/rfcs#227.

[@vue/compiler-sfc] When using experimental features,
it is recommended to pin your vue dependencies to exact versions to avoid breakage.

package.json内容如下：
{
"name": "my-vue-app",
"version": "0.0.0",
"scripts": {
"dev": "vite",
"build": "vite build"
},
"dependencies": {
"vue": "^3.0.5"
},
"devDependencies": {
"@vitejs/plugin-vue": "^1.0.4",
"@vue/compiler-sfc": "^3.0.5",
"vite": "^2.0.0-beta.12"
}
}

node 版本: v14.15.1

was there a resolution to this? I was getting the same “Does the file exist?” error but for /service-worker.js

[yyx990803]

service workers should be placed in /public

Same here, I don't use nor import any sw.js file, but vite out of the blue display that error

[yyx990803]

You probably loaded another app with service worker on the same localhost port before, and your browser is thinking it's the same app and attempting to request the service worker. You need to delete your service worker for that localhost port (from Chrome devtools' application tab). Or, use a different port so Chrome doesn't get confused.

Thank you @yyx990803, that was the error.

starting with vite 2.3.0 orphaned service workers produce a much noisier error message

[vite] Internal server error: The request url "/service-worker.js" is outside of vite dev server root "/my-app". 
      For security concerns, accessing files outside of workspace root is restricted since Vite v2.3.x. 
      Refer to docs https://vitejs.dev/config/#server-fsserveroot for configurations and more details.

Maybe vite should not try to fallback to fs root for paths without a directory structure? ie /foo/bar/baz.js would be searched for in and out of vite project root, but /baz.js only inside vite root.

There's another non-service-worker-related repro in sveltejs/kit#1420 using SvelteKit. Vite balks when the browser runs fetch('/api'). I feel this should get its own issue though.
