Thanks for submitting this issue! Due to our limited time, we ask you to include a reproduction link to a minimal full reproduction of your problem (for example in a GitHub repository) so we can find what is causing the issue. Thank you for your understanding!

@sodatea This is not a coding issue, the problem is that vue ui still adds baseUrl to the vue config file on save, but it has been deprecated and replaced by publicPath.

See https://cli.vuejs.org/config/#baseurl

So because it is deprecated, vue cli will create an error by its own generated file ^^.

This can easily be fixed by changing vue ui to update vue config file by publicPath instead of baseUrl.

Can't reproduce. And I can't find any reference to baseUrl in the Vue CLI UI codebase.

I've tried myself. I thought baseUrl has replaced by publicPath. Here's the screenshot.
