Question

I want to use yvoyer/CalendarBundle on my Symfony2.2 project.

I add it to composer.json and run:

composer update star/calendar-bundle --prefer-source

And it returns this error: 

$ composer update star/calendar-bundle --prefer-source
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

What is the cause of error? I'm thinking to fork the project and change the composer.json. But what should I put on it?

Was it helpful?

Solution

Just read the first 3 lines of the error:

- Conclusion: remove symfony/symfony v2.2.0
- star/calendar-bundle 0.1 requires symfony/symfony 2.0.* -> satisfiable by symfony/symfony[2.0.7, v2.0.10, v2.0.11, v2.0.12, v2.0.13, v2.0.14, v2.0.15, v2.0.16, v2.0.17, v2.0.18, v2.0.19, v2.0.20, v2.0.21, v2.0.22, v2.0.23, v2.0.9].
- star/calendar-bundle 0.1.1 requires symfony/symfony 2.1.* -> satisfiable by symfony/symfony[v2.1.0, v2.1.0-BETA1, v2.1.0-BETA2, v2.1.0-BETA3, v2.1.0-BETA4,v2.1.0-RC1, v2.1.0-RC2, v2.1.1, v2.1.10, v2.1.11, v2.1.2, v2.1.3, v2.1.4, v2.1.5, v2.1.6, v2.1.7, v2.1.8, v2.1.9].

That first line gives us an indication that the version of the symfony/symfony package is wrong. The 2 lines below it gives us the reasons why it's wrong:

  • version 0.1 requires Symfony 2.0.x
  • version 0.1.1 requires Symfony 2.1.x

So there is no support for 2.2.x.

What you should do if you want to use this bundle in 2.2:

  1. Fork the bundle and test it with sf 2.2
  2. Remove all deprecated stuff and make it comptable with 2.2
  3. Update composer.json to have something like symfony/symfony: 2.2.*
  4. Request a PR with the changes you made, let it merge and let the author of the bundle create a new version of the bundle and use that one in your composer.json
