Missing package errors typically look like: File 'xyz.sty' not found.

​
Common Causes

  • Typo or wrong package name.
  • Package not installed in local TeX distribution.
  • Outdated TeX distribution.
  • Template expects a package unavailable in your environment.

​
Fix Workflow

  1. Verify exact package name in docs.
  2. Remove duplicate/conflicting package calls.
  3. Update TeX distribution.
  4. In cloud editors, remove local-only package assumptions.
