首先，删除旧版本:

如果通过apt-get安装

sudo apt-get remove docker-compose

如果通过curl安装

sudo rm /usr/local/bin/docker-compose

如果通过pip安装

pip uninstall docker-compose

然后在GitHub的发布页面上找到最新版本，或者通过卷曲API并使用grep或jq从响应中提取版本(感谢dragon788, frbl和Saber Hayati的这些改进):

# curl + grep
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*\d')

# curl + jq
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)

最后，下载到您最喜欢的$ path可访问的位置，并设置权限:

DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION

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

这些解决方案大多已经过时，或者让您安装旧版本。 安装最新版本

sudo apt  install jq

DOCKER_COMPOSE_VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)

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

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。

下面是另一个使用curl和sed安装最新版本docker-compose的联机程序。

curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose

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
