安装swoft2.0.1报错及解决方案

安装swoft2.0.1报错如下：

Loading composer repositories with package information

Updating dependencies (including require-dev)

Your requirements could not be resolved to an installable set of packages.

  Problem 1

    - The requested PHP extension ext-redis * is missing from your system. Install or enable PHP's redis extension.

根据提示时php 缺少redis扩展。

解决方案：缺啥补啥。

1）下载扩展包：http://pecl.php.net/package/redis

2）执行如下操作，编译安装扩展包

tar -xzvf redis-4.3.0.tar

cd redis-4.3.0

/usr/local/opt/php@7.2/bin/phpize

./configure --with-php-config=/usr/local/opt/php\@7.*/bin/php-config

make

make install

vim /usr/local/etc/php/7.2/php.ini

添加扩展配置：

extension=/usr/local/Cellar/php@7.2/7.2.15/pecl/20170718/redis.so

保存配置文件后，查看PHP扩展是否正确安装

php -m
