安装

要安装 Zephir, 请按照下列步骤操作:

基础要求

要构建PHP扩展并使用Zephir，您需要满足以下要求：

  • Zephir parser >= 1.1.0

  • A C编译器，例如 gcc </ 0» = 4.4或替代方法，例如 clang </ 1» = 3.0， Visual C ++ </ 2» = 11或 Intel C ++。 建议使用 gcc 4.4 或更高版本</li>

    • re2c 0.13.6 或更高版本
  • PHP development headers and tools</ul>

对于基于 linux 的系统, 您还需要:

  • GNU make 3.81 or later
  • autoconf 2.31 或更高版本
  • automake 1.14 或更高版本
  • libpcre3
  • 在 ubuntu 上 gcc 时使用build-essential 包 (也可能在其他发行版中使用)

如果您使用的是 ubuntu, 则可以通过以下方式安装所需的包:

sudo apt-get update
sudo apt-get install git gcc make re2c php php-json php-dev libpcre3-dev build-essential

请注意，阅读本指南时特定版本的库和程序可能有所不同。

由于Zephir代码的编写是在PHP中进行的，所以需要安装最新版本的PHP，并且必须在您的控制台中可用:

php -v

PHP 7.2.17-0ubuntu0.19.04.1 (cli) (built: Apr 18 2019 18:01:25) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.17-0ubuntu0.19.04.1, Copyright (c) 1999-2018, by Zend Technologies
    with Xdebug v2.6.1, Copyright (c) 2002-2018, by Derick Rethans

此外, 请确保您在安装 php 的同时安装了 php 开发库:

phpize -v

Configuring for:
PHP Api Version:         20170718
Zend Module Api No:      20170718
Zend Extension Api No:   320170718

您不必确切看到的以上输出，但是这些命令对于开始使用Zephir进行开发非常重要。

安装 Zephir

首先, 确保安装并激活了 Zephir 解析器扩展。 You can follow this tutorial.

Using PHAR

The recommended, officially supported, and easiest-to-use way to install Zephir is to simply grab the latest release PHAR from GitHub, and download/move it to somewhere in your $PATH. You’ll probably also want to rename it to drop the .phar extension, so you can run it as zephir instead of zephir.phar.

Using Composer

The PHAR isn’t available before 0.11.4, so if you need an older version, you can use Composer, in one of two ways:

As a Global Composer Application

composer global require phalcon/zephir

There are two approaches to running Zephir at this point. The first is to ensure that ${COMPOSER_HOME}/vendor/bin is in your $PATH, then Zephir should be available as zephir on the command line. The second is to simply use composer global exec zephir instead.

As a Project Dependency

composer require phalcon/zephir

Use composer exec zephir within the project you installed Zephir in, above, to run it. (Alternately, you can still run vendor/bin/zephir.)

Using Git

Finally, you can also simply clone the latest tag from GitHub, install the dependencies, and run Zephir from there:

git clone --depth 1 -b $(git ls-remote https://github.com/zephir-lang/zephir 0.11.* | sort -t/ -k3 -Vr | head -n1 | awk -F/ '{ print $NF }') https://github.com/phalcon/zephir
composer install

You’ll need to either use the path to zephir/zephir, or create a symlink in a directory in your $PATH, to run Zephir using this option.

测试安装

检查Zephir是否可以从任何目录执行:

zephir list
