研究方向
Investigate how Yarn handles 'file:' protocol dependencies in its caching mechanism. Look at the source files related to package fetching and caching, such as 'src/package fetcher.js' and 'src/package cache.js'. Identify where the node modules directory is copied during the add process and determine the condition that should exclude copying for 'file:' dependencies. The issue mentions version 0.23.4, so check the codebase at that tag for relevant logic. No existing PRs or comments provide further direction.
