Changing `root` property in `vite.config.js` is breaking the project.

**Description of Bug**

I organize my codebase by moving all the source code, including the entry points in the `src` directory. And I set the `root` property of the vite config to `"src"` to achieve this.

With this setup when I run the dev server or build/generate, it tries to reinstall abell and ends with an error.

I tried another approach by using `vite` directly with `vitePluginAbell` and that didn't worked out either.

```
project-dir
|- src
| |- index.abell
| |....
|- public (public assets)
|- package.json
|- vite.config.js
|- ...other config files
```

**Steps To Reproduce**

1. modify the `root` property in `vite.config.js`
2. run the dev server
