We have used vuejs dependencies in shop, admin and ui packages.
If you go to shop package use the command:
npm install (to install npm dependencies)
npm run dev
This will break down the production cycle and then you can see the vuejs tab.
Another possibility of this situation is that you must have messed with order of JS files used on your layout file. Make sure shop.js is used first and then ui.js.
If you still face any issues then file a ticket at
[email protected] so we will inspect the issue even deeper.
