我按照指南中所述执行所有操作，但我得到

我该怎么办请帮忙！

Answer 1

这个问题由 docker 回答，它自行检查此页面 ，您可以手动安装插件

要下载并安装 Compose CLI 插件，请运行：

 DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
 mkdir -p $DOCKER_CONFIG/cli-plugins
 curl -SL https://github.com/docker/compose/releases/download/v2.12.2/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose

此命令下载最新版本的 Docker Compose（从 Compose 版本存储库）并在$HOME目录下为活动用户安装 Compose。

安装：

为系统上的所有用户使用 Docker Compose，替换~/.docker/cli-plugins为/usr/local/lib/docker/cli-plugins. 不同版本的 Compose，请将 v2.12.2 替换为您要使用的 Compose 版本。对二进制文件应用可执行权限：

 chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose

或者，如果您选择为所有用户安装 Compose：

 sudo chmod +x /usr/local/lib/docker/cli-plugins/docker-compose

测试安装。
