I upgrade Symfony to the 5.0 version.

When I run the server, all is right. However, when I use composer (example composer remove tattali/calendar-bundle), I get these errors :

    C:\cmder\roadtrip>composer remove tattali/calendar-bundle
    Dependency "symfony/framework-bundle" is also a root requirement, but is not explicitly whitelisted. Ignoring.

Removal failed, reverting ./composer.json to its original content.

I don't understand what I must do to solve this problem.

EDIT :

I updated Php to the last version, I resolved all depreciations, I changed the doctrine-extensions bundle to a bundle supported by Symfony 5. Now, I get theses errors :

  • No, I don't have a a solution. I updated Php to the last version, I resolved all depreciations, I changed the doctrine-extensions bundle to a bundle supported by Symfony 5 but I always have this kind of error messages. – Christophe Dubois Mar 01 '20 at 11:38
  • When I execute "composer update", I get the same errors. – Christophe Dubois Mar 01 '20 at 12:14
  • Create a new Symfony 5 project then run "composer require tattali/calendar-bundle" and see what happens. If you get errors then you know the bundle has not been updated for S5. You can check on github to see if an update is at least scheduled. If no errors then at least you know the problem is elsewhere. Symfony and Composer work well for minor updates but major updates can be problematic. – Cerad Mar 01 '20 at 14:43
  • It being a lazy Sunday morning I went ahead and followed by own suggestion. No errors. Now you should continue to install any other third party bundles your app uses. If they all install cleanly then you can replace your existing composer.json with the new composer.json. – Cerad Mar 01 '20 at 14:49
  • Can you share your composer.json please – Gary Houbre Mar 02 '20 at 07:11

I resolved my problem by removing the webserver bundle.
