首先，我本地的环境是 Mac + PHP 7.4.21 + Swoole Version => 4.6.7 + Composer version 2.4.4，作为学习，建议大家统一选择官方的 docker 镜像。
我们先在本地创建一个目录，这个目录会直接映射到 hyperf 容器的 /data/project 目录。
~ » cd /data/work
/data/work » mkdir questions_learn执行下面的命令安装 hyperf 镜像，可能需要等待几分钟等待时间（如果本地没有这个镜像的话）。
docker run --name hyperf-php-8.0 \
-v /data/work/questions_learn:/data/project \
-p 9501:9501 -it \
--privileged -u root \
--entrypoint /bin/sh \
hyperf/hyperf:8.0-alpine-v3.15-swoole在这一步中，大家记得把 -v 后面的 "/data/work/questions_learn" 改成你本地的目录，其他的保持不变。
上面的安装命令执行成功后，我们就已经在 hyperf 容器内了，来一起看下 hyperf 容器内的环境。

将 Composer 镜像设置为阿里云镜像，加速国内下载速度
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer 可以看到，官方镜像默认支持了很多扩展，如果你选择自己本地的环境，请至少确保你的运行环境达到了以下要求：
- PHP >= 8.0 and <= 8.1
- Swoole PHP 扩展 >= 4.5，并关闭了 Short Name
- JSON PHP 扩展
- Pcntl PHP 扩展
- enabled swoole coroutine、openssl、curl-native、async_redis、rwlock、pcre、zlib、brotl
另外，由于 Hyperf 基于 Swoole 协程实现，而 Swoole 4 带来的协程功能是 PHP 前所未有的，所以与不少扩展都仍存在兼容性的问题。
以下扩展（包括但不限于）都会造成一定的兼容性问题，不能与之共用或共存：
- xhprof
- xdebug
- blackfire
- trace
- uopz
这些我们基本也用不上，推荐大家按照文中的操作，选择官方镜像。
下面我们继续在容器内操作。
创建一个项目，并命名 questions
/ # cd /data/project/
/data/project # composer create-project hyperf/hyperf-skeleton questions执行 composer create-project 命令的时候，开始会一直提示我们安装一大堆东西，直接全部回车，后面需要我们再手动进行安装。
安装好之后，安装的 hyperf 还是 2.2 版本，通过 composer info 命令可以查看已安装的 hyperf 相关的版本信息。

接下来大家可以参考官方的升级指南，也可以跟着当前教程继续操作。
composer require hyperf/code-generator
php bin/hyperf.php code:generate -D app直接将 composer.json 中的 hyperf/ 统一修改为 3.0. ，然后执行 composer update -o，现在我们重新看下 hyperf 相关的版本信息。

本地我们先按照这个模式走，后期上线会全自动操作，这点无需担心。
窗口卡着不动即表示安装成功。
以上，我们都是在容器内执行的命令操作。（将 composer.json 中的 hyperf/ 统一修改为 3.0. ，这个大家可以在宿主机用 ide 进行编辑修改，编辑的是本地的 /data/work/questions_learn/questions/composer.json 文件）
回到宿主机内，对本地的 9501 端口请求测试。
/data/work » curl 127.0.0.1:9501
{"method":"GET","message":"Hello Hyperf."}%至此，hyperf 框架已经安装完毕。
