After I created a project with the vue cli vue create myTest, I got the error inside of the router.ts file:

But both types are installed properly: node_modules/@types/jest and node_modules/@types/webpack-env.
Using Windows 10 with NetBeans 10 and NBTS 3.0.1.
I restarted NetBeans and changed the TypeScript setup from the global installed TS to the local one, nothing helped.
