What is the expected behavior?

The binary is being installed to AppData\Local\Yarn\bin\create-foo however yarn create is trying to execute a file with the @scope in the path. This is a regression from 1.7.0 where this worked properly.

Please mention your node.js, yarn and operating system version.
