[FIXED] Installing composer programatically working on vagrant but not on EC2 instance

Issue

I'm working on Ansible playbook. When provisioning on a vagrant machine, it goes well, without errors. Right now I'm on a trouble on the step where composer is installed programatically.

install-composer.sh (This script has been taken from Composer Page)

#!/bin/sh

EXPECTED_SIGNATURE="$(wget -q -O - https://composer.github.io/installer.sig)"
echo $EXPECTED_SIGNATURE;
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_SIGNATURE="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"
echo $ACTUAL_SIGNATURE; <- Here is empty!

if [ "$EXPECTED_SIGNATURE" != "$ACTUAL_SIGNATURE" ]
then
    >&2 echo 'ERROR: Invalid installer signature'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --quiet
RESULT=$?
rm composer-setup.php
exit $RESULT

The EC2 is a Ubuntu 16.04 instance, on vagrant as well.

Playbook task where i'm getting the error:

 - name: Download Composer
      script: scripts/install_composer.sh
      register: composer_setup
      #when: not composer_stat.stat.exists
      tags:
        - deploy

And the full error with --verbose:

Any idea why this line is returning empty on ec2?

"$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

Thanks!

Solution

After Trying what Aaron Said, I saw that php was not correctly installed(not installed at all)

I was executing:

ansible-playbook ansible/playbook.yml -i ansible/hosts.ini -t deploy --ask-vault-pass --verbose

Note the tag deploy, so in here it is suposed that php was installed. All had to do was remove -t deploy from my command!
