Hi, have you solved it? Clear the composer cache doesn't help

[Solved] In my composer.lock was wrong info about this and any other packages yet. I have revert my changes with composer.json / composer.lock and it works for me. You can try:

1. Clear the composer cache
2. Remove the vendors
3. Change in composer.json version of packages to static (e.g 1.2.0) to avoid update of them
4. Remove composer.lock
5. Start composer install. Then it should work correclty ;)

Removing lock file will update all versions of everything in your app to the latest allowed by composer.json when you run composer install. Be careful with this. You want to avoid messing with the lock file manually generally.
