About

Debug Composer Conflicts

Workflow

  1. Run composer why-not or inspect Composer's solver output.
  2. Check PHP version, Laravel version, package constraints, minimum stability, and plugin allowances.
  3. Confirm whether security advisories are blocking a version.
  4. Prefer updating constraints honestly over forcing ignored advisories.
  5. Update docs and CI matrix when support changes.
  6. Re-run composer update --dry-run or the intended install/update command.

Verification

  • composer validate passes.
  • The intended composer require or composer update succeeds.

Common Mistakes

  • Pinning an old vulnerable framework version.
  • Adding broad constraints without testing each supported lane.
