I am trying to install phalcon in aws beanstalk with 64bit Amazon Linux 2016.03 v2.1.4 running PHP 5.5.

deployed code with .ebbeanstalk which has following code

commands: 01_phalcon_install:

run this command from /tmp directory

    cwd: /tmp
    # don't run the command if phalcon is already installed (file /etc/php.d/phalcon.ini exists)
    test: '[ ! -f /etc/php.d/phalcon.ini ] && echo "phalcon not installed"'
    # executed only if test command succeeds
    command: |
        git clone --depth=1 git://github.com/phalcon/cphalcon.git \
        && cd cphalcon/build \
        && ./install \
        && echo extension=phalcon.so > /etc/php.d/phalcon.ini \
        && rm -rf ./cphalcon

It gave following error

[Instance: i-5693e58b] Command failed on instance. Return code: 128 Output: fatal: destination path 'cphalcon' already exists and is not an empty directory. command 01_phalcon_install in tpk/.ebextensions/02_phalcon.config failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

any one can help me with this error
