`vue-tsc --noEmit` fails right after adding "webworker" to tsconfig.json as a lib

[Ky6uk]

I've tried to add PWA support to Vue 3 app with vite-plugin-pwa. It looks like the plugin requires "webworker" library that should be added to the lib section into tsconfig.json. But right after doing this the command vue-tsc --noEmit starts failing.

The project had been generated with npm init vite.

• @vitejs/plugin-vue: v1.2.5
• typescript: v4.3.5
• vite: v2.4.2
• vue: v3.1.4
• vue-tsc: v0.0.24

This is same output with executing tsc --noEmit, it's not vue-tsc problem. I think "webworker" is conflict with your other settings in lib section.

@johnsoncodehk Thanks, I haven't tested with tsc. It looks like the problem exists for years in TypeScript.
