vue dev tools not working with vue-cli project

Question

I've installed new vue-cli project and when launched locally and opened on localhost:8080 by running

npm run serve

Vue dev tools stayed inactive. I've read that one needs to initialize Vue instance, in order for it to work, but with vue-cli, app is initialized with createApp, but not with Vue instance.

Answer 1

It was my bad. I've accidentally used vue v3 instead of v2. After switching back to 2 version, works fine.
