Trouble installing with composer

[YamilBracho]

Hi.
I am tryoing to install fluid via composer but I got

[InvalidArgumentException]
Could not find package servo/fluidxml at any version matching your PHP vers
ion 5.5.38.0

Which version of php is requiered ?

TIA,
Yamil

As stated in the composer file, the minimum required version is 5.6. The library makes heavy use of variadic functions, which are new to PHP 5.6.

Yes!!
My mistake ... I should have read the documentation first... :-)

Thanks a lot!!
