Problems with lib-icu dependency when installing Symfony 2.3.x via Composer

Question

I\'ve had no problems installing Symfony 2.2.x using Composer, I\'ve always just copied the stable version at http://symfony.com/download.

composer create-pr

A solution regarding this or similar problems can be found here: ICU and Deployment Problems

The behavior of composer should be intelligent selecting the right icu-component:

• symfony/icu 1.0.*: when the intl extension is not available
• symfony/icu 1.1.*: when intl is compiled with ICU 4.0 or higher
• symfony/icu 1.2.*: when intl is compiled with ICU 4.4 or higher

There should be (theoretically) no error installing symfony 2.3. with no intl-extension.

But you can be trapped when your development-environment differs from your production-server like mentioned in this article:

• the development machines are compiled with ICU 4.4 or higher, but the server is compiled >with a lower ICU version than 4.4
• the intl extension is available on the development machines but not on the server.

When you have no root-access to your production-server you can fix it as mentioned in this article. (tweaking composer.json)

Hope this additional information helped as it helped me for this special case with different environments.
