Research direction: Investigate the yarn install flow where it executes git pull in the cache directory. Look at the file `src/util/git.js` or the code that runs git commands. Determine if there is a missing check for the global git configuration before running git pull. Consider using git with dummy credentials or skipping git operations when no user is set. Review the existing comments for any proposed fixes.
