Is there a way to make this work with Packer?

I'm using a lua based neovim config and Packer as my plugin manager. For some reason I'm not able to get this plugin to work when using it directly, but it does work with vim-polyglot.

I'm simply adding it like so:

```
require('packer').startup(function(use)
...
  use({ 'posva/vim-vue' })
...
end)
```

Any ideas why it might not be working?
