  • Review Composer Lock File: Inspect the composer.lock file to ensure it’s up-to-date and consistent with the composer.json file:
  • Resolve Dependency Version Conflicts: Try upgrading or downgrading particular dependencies in your composer.json file if you run into version issues. Next, sprint:
  • Clear Composer Cache: Clear Composer’s cache to resolve any caching issues:

Prior to making any significant changes, always make a backup of your project, especially before editing composer.json or reinstalling dependencies. If these procedures don’t solve your problems, you could choose to hire a professional developer or ask the Composer community for help in additional troubleshooting.
