"Unexpected token error" with vue add vuetify

[sarahLardeau]

I encoutered an error on vue add vuetify command and managed to find a simple scenario to reproduce the issue.

Steps to reproduce :

• Create a new vue project with @vue/cli-services: 4.1.1 with this config (basic with typescript) :
  

• Add the following code in main.ts
  Vue.config.errorHandler = (err: Error, vm: Vue, info: string) => { // For some crash tracking config like Sentry };
  

• Then run : vue add vuetify and select the default preset

You will see a nice parser error

If you remove the code added to main.ts it works perfectly ;)

I cannot reproduce this. Can you provide a repository?

Likely a bug with vue-cli itself: vuejs/vue-cli#4861
