Sylius Fresh Installation: can't install "sensio/generator-bundle"?

Question

I am new to Sylius and I have just installed a fresh Sylius project on my Mac, it is working fine. Then I realised that I need to create my own bundle under src to overwrite the Sylius bundles. Usually, I will use "php app/console generate:bundle" to generate a bundle skeleton, but the "sensio/generator-bundle" is not integrated with the default Sylius project so I will need to install it first via composer, but it seems I couldn't do that because of the dependency error, below is the error result

Is it possible to install the generator bundle or is there another way to create a bundle?

Thanks

Answer 1

This is the important line in the error message: sensio/generator-bundle v2.5.0 requires symfony/console ~2.5 Followed by Conclusion: remove symfony/symfony v2.3.25

This means: (a) you have Symfoy 2.3.25 installed and (b) you want to require a version of the SensioGeneratorBundle which requires at least Symfony 2.5.

You can solve it in 2 ways:

• Bump the Symfony version constraint to ~2.5
• Require a version of the SensioGeneratorBundle that is compatible with Symfony 2.3.
