Установка модуля pthreads php Ubuntu

Пытался установить composer Ввожу команду php composer.phar install и выдает следующую ошибку

Do not run Composer as root/super user! See https://getcomposer.org/root for details
Loading composer repositories with package information

  Problem 1
    - The requested PHP extension ext-pthreads >=3.1.7dev is missing from your system. Install or enable PHP's pthreads extension.

Пробовал установить pthreads так pecl install ptreads

выдает следующее

checking for ZTS... configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled

ERROR: `/tmp/pear/temp/pthreads/configure --with-php-config=/usr/bin/php-config' failed
