1.进入https://github.com/docker/compose/releases 查看最新版本，当前版本为1.23.1

sudo curl -L https://github.com/docker/compose/releases/download/1.23.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

2.设置权限

sudo chmod +x /usr/local/bin/docker-compose

3.查看是否安装成功

docker-compose --version

如果报 [12147] Cannot open self /usr/local/bin/docker-compose or archive /usr/local/bin/docker-compose.pkg  应该是包没下载完整，1、2、3步骤再来一遍。
