Details

Idk what's wrong here.

It complains when checking process.env.IS_REACT18.

If modern.config.js set disableNodePolyfill=false, then the error goes away, but process.env.IS_REACT18 is still not correctly set.

Reproduce Steps

cd apps/app
pnpm dev

Then open the browser.

The cause:
In a pnpm workspace, I install @modern-js/app-tools at the root folder. Therefore, its internal appDirectory is resolved the root folder. Then modernjs tries to read its package.json to find the react version.
If I execute the command in a workspace folder which installs React 18, then it could not be correctly resolved.
Add @modern.js/app-tools as dependency of workspace folder can fix the issue.
