TypeScript errors out of the box

I have a Vue project with TypeScript, and just with this code block I’m getting a type error:

Argument of type 'PluginFunction<any>' is not assignable to parameter of type 'PluginObject<any> | PluginFunction<any>'.

import Vue from 'vue';
import Vuelidate from 'vuelidate';

Vue.use(Vuelidate);

I had the same problem with similar tsconfig.json. I used yarn in project. As playgound worked fine and neighter deleting node_modules and reinstalling did not helped I expected some tsconfig issue. After some hours of many changes of tsconfig and googling, I found Jan Esser’s comment about two versions of vue in project (https://github.com/vuelidate/vuelidate/pull/287). Confirmed that this was the case.

Problem was caused by yarn duplicates of vue package in yarn.lock. Helped using yarn-deduplicate to fix duplicates followed by yarn install. It worked correctly now. Thank you Jan for good job.

@mvandak thanks, works fine. After that, close and re open VSC to get the changes.
