Nothing happens when I enter the following line into the terminal:
php composer.phar update
The same for installation or any other option.
What could be the problem? I am working on CentOS. Thanks
Usually, if nothing happens, this is due to an incorrect configuration, and you can check the configuration problems by running the setup program again in test mode:
curl -sS https://getcomposer.org/installer | php -- --check
If the @Seldaek installer check recommends working fine and you are in a chroot environment , this should save your ass (that was mine):
/usr/share/zoneinfo chroot.
/usr/share/zoneinfo
github.
