Unexpected token when running vue add

[gnuletik]

Hi !
I'm currently unable to add the plugin to a project built with @vue/composition-api and typescript.

I get the following error after running vue add:

 ERROR  SyntaxError: Unexpected token, expected "]" (23:19)

$ vue -V
@vue/cli 4.3.1

$ vue add vue-next

Here's the reproduction repo :

Is it somehow related to Typescript ? I know it is not supported yet but I've seen it can be run in the following issue #7

Thanks for this tool :)

Same for me as well.

[VottusCode]

I have the exact same issue.

My current dependencies:

Output:

@VottusCode With Vue CLI 4.5, you don't need this plugin anymore.

@VottusCode With Vue CLI 4.5, you don't need this plugin anymore.

I wanted to update an existing application to Vue 3.
Nevermind that, even with Vue CLI 4.5, with vue create it still installs Vue 2.6.12 without the option to use Vue 3.

And yes, I do have the latest version of Vue CLI globally installed.

I have the Vue 3 option with 4.5.0 ("choose vue version")
