Error al instalar CakePHP 3.0 usando el compositor

Traté de instalar cakephp 3.0 en ejecución:

composer create-project -s dev cakephp/app cakedev 

y también git clonando cakephp / app y luego ejecutando la actualización del compositor, pero sigo recibiendo el mismo error:

Intenté ejecutar los commands usando sudo y también obtuve el error.

¿Algunas ideas?

Elimina la memory caching del compositor en ~ / .composer / cache / * y trata de boost el time de espera del compositor con estos methods

Pruebe con la opción –prefer-dist si no funciona intente boost el time de espera del compositor (valor pnetworkingeterminado il 300)

 export COMPOSER_PROCESS_TIMEOUT=600 php composer.phar install --prefer-dist 
 composer clearcache composer clear-cache 

Solo para aclarar Las líneas anteriores están construidas para borrar la caching del compositor. Ambos commands son iguales.
