Not sure what the point of failure is. NVM? Node version? Messed up permissions?

Appreciate any help getting this sorted!

This issue might be a duplicate of existing issues. Please check:

• Postinstall fails on Windows: Missing opencode-win32-x64 package during global install #1192: Windows postinstall failure with missing native packages and permission errors during npm global install
• Windows Support #631: General Windows support tracking issue for installation and permission problems

The error messages you're seeing appear to be related to npm's console output parsing rather than the actual permission errors. Your real issue seems to be the EPERM symlink creation failure mentioned at the end. Feel free to ignore if none of these address your specific case.
