The Zephir Parser extension is not loaded.

For a new zephir , I installed a new ubuntu 16.04 and follow this page (https://docs.zephir-lang.com/en/latest/install.html) to setup.

When I try to build , the error message is

[email protected]:~/zephir/utils$ zephir build [Zephir\Exception\IllegalStateException]:

──────────────────────────────────────────────────────────── The Zephir Parser extension is not loaded. Note: Zephir no longer distributed with internal parser.

To install latest stable Zephir Parser please refer to: https://github.com/phalcon/php-zephir-parser ────────────────────────────────────────────────────────────
