Hi,

I have a Vue2 project, where components are written in JavaScript or TypeScript.

Without setting allowJs to true in tsconfig.json, there is a message Virtual script not found, ...

After I set allowJs to true in tsconfig.json, Virtual script not found messages in js .vue file have gone.
But in ts .vue file, TS2304 errors are reported by vue-tsc and VSCode.

Here is the repository for reproduction, and version information is as the following.

  • typescript v4.4.4
  • vue v2.6.14
  • vue-tsc v0.29.8
  • @vue/runtime-dom v3.2.25

Similar issue I found: #319
