Using vue-property-decorator and "default" string causes error #27

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:

Update

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

Seems to be related to

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

After updating to vue@2.7.10 the issue is gone: https://stackblitz.com/edit/vue2-vite-starter-th6fyw?file=package.json

@CreMindES This might had fixed it in 2.7.9 according to the changelog: https://github.com/vuejs/vue/pull/12747
