Cannot find module 'semver'

While ns run android --clean I kept getting this error after upgrading to version 8.

Webpack compilation complete. Watching for file changes.

I was only able to proceed after installing semver manually by doing npm i semver

I think this should not have been required and there is something not right.

Start with @nativescript/core/cli-hooks/before-checkForChanges.js and the related hooks/before-checkForChanges/nativescript-core.js entry point, then inspect how the NativeScript CLI resolves dependencies during ns run android --clean. Confirm the clean command completes without requiring a manual npm i semver.
