我已经在CentOS 7上安装了docker，运行如下命令:
curl -sSL https://get.docker.com/ | sh
systemctl enable docker && systemctl start docker
docker run hello-world
注意:helloworld运行正常，没有问题。
然而，当我试图运行docker-compose (docker-compose。yml存在并且有效)它只在CentOS上给了我错误(Windows版本的docker-compose文件工作良好)
/usr/local/bin/docker-compose: line 1: {error:Not Found}: command not found

对于Ubuntu操作系统有很多建议，但我认为最简单的解决方案是创建一个别名。(如果docker compose已经安装)
步骤:
Ls -la在~目录中查看是否有.bash_aliases 如果不直接创建它(触摸，纳米…或者简单地使用gedit) gedit .bash_aliases (以上步骤可以跳过，只需在.bashrc中添加你的别名) 添加别名别名docker-compose="docker compose" 使别名在当前会话中可用:source ~/.bashrc

官方文件显示:
如果您为Windows或Mac安装了Docker Desktop/Toolbox，则您需要 已经有Docker Compose!Play-with-Docker实例已经有了 Docker Compose也安装了。如果您使用的是Linux机器，那么您 需要安装Docker Compose。
为此，您需要参考预先存在的Docker安装部分。
我正在安装树莓派3，在树莓操作系统上。curl方法没有解析为有效响应。它还说{错误:未找到}，我看了一下URL https://github.com/docker/compose/releases/download/1.11.2/docker-compose-Linux-armv7l，它是无效的。我猜那里没有建筑。
这个指南https://github.com/hypriot/arm-compose对我很有用。
sudo apt-get update
sudo apt-get install -y apt-transport-https
echo "deb https://packagecloud.io/Hypriot/Schatzkiste/debian/ jessie main" | sudo tee /etc/apt/sources.list.d/hypriot.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 37BBEE3F7AD95B3F
sudo apt-get update
sudo apt-get install docker-compose
参考上面给出的答案(我没有足够的声誉单独提到单独的解决方案，因此我在这里集体做这些)，我想补充一些重要的建议:
docker-compose you can install from the repository (if you have this package in the repository, if not you can adding to system a repository with this package) or download binary with use curl - totourial on the official website of the project - src: https://docs.docker.com/compose/install / docker-compose from the repository is in version 1.8.0 (at least at me). This docker-compose version does not support configuration files in version 3. It only has version = <2 support. Inthe official site of the project is a recommendation to use container configuration in version 3 - src: https://docs.docker.com/compose/compose-file / compose-versioning /. From my own experience with work in the docker I recommend using container configurations in version 3 - there are more configuration options to use than in versions <3. If you want to use the configurations configurations in version 3 you have to do update / install docker-compose to the version of at least 1.17 - preferably the latest stable. The official site of the project is toturial how to do this process - src: https://docs.docker.com/compose/install/ when you try to manually remove the old docker-compose binaries, you can have information about the missing file in the default path /usr/local/bin/docker-compose. At my case, docker-compose was in the default path /usr/bin/docker-compose. In this case, I suggest you use the find tool in your system to find binary file docker-compose - example syntax: sudo find / -name 'docker-compose'. It helped me. Thanks to this, I removed the old docker-compose version and added the stable to the system - I use the curl tool to download binary file docker-compose, putting it in the right path and giving it the right permissions - all this process has been described in the posts above.

尝试在CentOS上使用curl per docker docs安装docker-compose(适用于Linux)。在这些步骤之后，它返回一个错误
docker-compose -v
/usr/local/bin/docker-compose: line 1: Not: command not found
有趣的是，docker-compose文件在第一行只包含“Not Found”(它应该是二进制文件)
cat /usr/local/bin/docker-compose
Not Found
这意味着我试图从github链接卷曲不存在。我失败的链接是:
sudo curl -L "https://github.com/docker/compose/releases/download/2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
在本地运行uname -s和uname -m可以看到需要添加到下载url中的内容
uname -s
Linux
uname -m
x86_64
在浏览器中尝试url https://github.com/docker/compose/releases/download/2.2.2/docker-compose-linux-x86_64 显示未找到该页面。
一个他们在版本中添加“v”的问题，如v2.2.2。所以下载url应该是v https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64。他们的发布:https://github.com/docker/compose/releases/
这是有效的(注意v2.2.2)
sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v
Docker Compose version v2.2.2
如果你通过将docker的官方存储库添加到存储库列表来安装docker，如下所示:
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
只做:
$ sudo apt-get install docker-compose
对于基于RHEL的发行版/ Fedora:
$ sudo dnf install docker-compose
