Using vue-property-decorator and "default" string causes error

[rs3d]

Hi,

I'm experiencing a strange issue.
Whenever I use default as class prop or even as a string like defaultSomething in a JS-comment in my .vue-files, the following error shows up:

Error:

DEMO: https://stackblitz.com/edit/vue2-vite-starter-gkrjjz?file=src/components/Test.vue
Exporting an interface in combination with the string 'defaultXXX' inside a comment shows the error.

I assume that this line is causing the error:
at genScriptCode (\app\node_modules\@vitejs\plugin-vue2\dist\index.cjs:2993:37)
Code
scriptCode = options.compiler.rewriteDefault(script.content, "_sfc_main", [...defaultPlugins, ...userPlugins]);

Also happening for me, but with Vite version v2.9.14, and Vue version v2.7.8.

I can also reproduce this on

• Vue 2.7.8
• Vite 3.0.7
• @vitejs/plugin-vue2 1.1.2

Seems to be related to

• fix(compiler-sfc): make sure rewriteDefault get correct result when use decorator before export default (fix #6318) vuejs/core#6320

as when moving the default export [className] after the class declaration, everything works nicely.

After updating to [email protected] the issue is gone:

@CreMindES This might had fixed it in 2.7.9 according to the changelog:
vuejs/vue#12747
