Property 'XXX' does not exist on type 'CombinedVueInstance>>'

Question

I created a vue component with TypeScript, and I\'m getting this error in data() and in methods():

Property \'xxx\' does not exist          


        

Answer 1

This seems to be inexplicably caused by using this.$store to compute the return value of profilePath, combined with the unspecified return type on its declaration.

One workaround is to specify the return type as string:

profilePath: function(): string {

verified with npm run serve and npm run build, using Vue CLI 3.7.0 on macOS Mojave
