在mac上(也适用于ubuntu):

sudo curl -L "https://github.com/docker/compose/releases/download/<release-version>/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

注意:写在这里: https://github.com/docker/compose/releases

在研究了很多方法之后，我最终使用了jq，希望我可以扩展它来处理Docker-Compose之外的其他回购，而不需要太多的工作。

# If you have jq installed this will automatically find the latest release binary for your architecture and download it
curl --silent "https://api.github.com/repos/docker/compose/releases/latest" | jq --arg PLATFORM_ARCH "$(echo `uname -s`-`uname -m`)" -r '.assets[] | select(.name | endswith($PLATFORM_ARCH)).browser_download_url' | xargs sudo curl -L -o /usr/local/bin/docker-compose --url

我试图在“Ubuntu 16.04.5 LTS”上安装docker-compose，但安装后像这样:

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

我得到:

-bash: /usr/local/bin/docker-compose:拒绝权限

当我使用它与sudo我得到:

Sudo: docker-compose:命令不存在

下面是我解决问题的步骤:

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo ln -sf /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

如果你尝试sudo apt-get remove docker-compose并得到E: Unable to locate package docker-compose，请尝试以下方法:

这个命令必须返回一个结果，以便检查它是否安装在这里:

ls -l /usr/local/bin/docker-compose

删除旧版本:

sudo rm -rf docker-compose

下载最新版本(查看官方repo: docker/compose/releases):

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

(如有需要，替换1.24.0)

最后，对二进制文件应用可执行权限:

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

检查版本:

docker-compose -v

基于@eric-johnson的回答，我目前正在一个脚本中使用这个:

#!/bin/bash
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
output='/usr/local/bin/docker-compose'
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$(uname -s)-$(uname -m) -o $output
chmod +x $output
echo $(docker-compose --version)

它从GitHub api获取最新版本。

如果以上方法对你不起作用，那么参考这个答案:https://stackoverflow.com/a/40554985

curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" > ./docker-compose
sudo mv ./docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
