[a20185]

Describe the bug

When adding reactivue in existing React16 projects, we found the reactiveness lost in demo.

1. install [email protected] in project
2. follow useSetup demo, create a simple counter function component with ref/computed
3. mount the component, and call inc function
4. view never rerendered

The project https://github.com/a20185/reactivue-bug repro the same bug, by following steps:

1. clone the repo
2. yarn install
3. yarn start
4. click the counter

@antfu @CJY0208 any ideas on this problem? It seemed the code never reach reactivue land. When I'm trying to add breakpoints in callback functions in doWatch and effects in useSetup implementation, it never trigger watch or effect when using inc to modify values.

I noticed that there are multiple versions of @vue/* in your lock file. Try aligning the versions in package.json through "resolutions", and then see if the problem disappears.

// package.json
{
  ...
  "resolutions": {
    "@vue/reactivity": "3.1.5",
    "@vue/runtime-core": "3.1.5",
    "@vue/shared": "3.1.5"
  }
  ...
}
