no exported member 'ref'

[mnlipp]

Version

3.2.11

Reproduction link

github.com

Steps to reproduce

Use typescript.

import { App, Ref, ref } from 'vue'

Observe the error. Removing "Ref" and "ref" makes it work ("App" can be imported"). But importing either "ref" or "Ref" results in the error: Module '"../node_modules/vue/dist/vue"' has no exported member ...

This worked without problems in 3.1.1.

What is expected?

Should compile.

What is actually happening?

Yes, please provide a minimal reproduction as required in the issue guidelines. We can't debug your actual projects.

Problem was caused by typescript compiler being too old (3.9.10). Upgrading to current (4.4.3) fixes it.

Well, thanks for the "thumbs up". I've pondered some time whether to add another comment. Here it is: I think the requirement for a higher typescript version should have been mentioned as a breaking change.

I don't know why google didn't show this one before (I did search before posting this issue), but obviously I'm not the only one who has spent time on this.
