Sylius Install issue: "Your requirements could not be resolved to an installable set of packages"

[sepehr3point]

Hi folks

I am getting this error message when trying to create a new Sylius project.
Would you please help me get this fixed?...
Here are the commands that I have tried so far and both comes up with same results:

composer create-project sylius/sylius-standard -s dev
composer create-project -s beta sylius/sylius-standard

result:

To enable extensions, verify that they are enabled in your .ini files:
- C:\Bitnami\wampstack-5.6.29-0\php\php.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

league/uri 4.2.1 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.

Looks like you're missing an extension.

To enable extensions, verify that they are enabled in your .ini files:
- C:\Bitnami\wampstack-5.6.29-0\php\php.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.
