sudo: docker-compose:未找到命令

Question

我正在尝试使用sudo运行docker-compose。

我在Ubuntu 16.01上安装了docker和docker-compose。

由于尝试使用curl下载compose时出现错误，我最终使用pip进行了安装。

Docker版本1.12.0，内部版本8eab29e docker-compose版本1.8.0，内部版本94f7016

然而，当我尝试使用sudo运行docker-compose时，我得到了以下结果(使用sudo和docker可以)

sudo: docker-compose: command not found

我想对于“已安装”的含义有不同的定义。我一直在同一台声称没有安装docker-compose的计算机上使用docker-compose。

$ dpkg -s docker-compose
dpkg-query: package 'docker-compose' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.


$ whereis docker-compose
docker-compose: /home/user/.local/bin/docker-compose

$ pip show --files docker-compose

Answer 1

在Ubuntu 16.04上

下面是我是如何解决这个问题的:请参阅Docker Compose documentation

1. sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
2. sudo chmod +x /usr/local/bin/docker-compose

执行curl命令后，它会将docker-compose放入

/usr/local/bin

它不在PATH上。要修复此问题，请创建符号链接：

1. sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

现在，如果你这样做了：docker-compose --version

您将看到docker-compose现在位于PATH上

Answer 2

dpkg -s ...的输出表明docker-compose不是从软件包安装的。如果你没有更多的信息，至少有两种可能性：

根本没有安装

1. docker-compose，您需要安装它。

这里的解决方案很简单: install docker-compose.

• docker-compose安装在您的$HOME目录中(或其他位置，而不是根目录的$PATH上)。

在这种情况下，有几种解决方案。最简单的可能是替换：

sudo docker-作曲...

通过以下方式：

sudo which docker-compose ...

这将使用docker-compose的完整路径调用sudo。

您也可以将docker-compose安装到系统范围的目录中，如/usr/local/bin.

Answer 3

如果您尝试通过官方docker-compose页面进行安装，则需要使用curl下载二进制文件：

curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

然后，不要忘记在二进制文件中添加可执行标志：

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

如果使用python-pip安装docker-compose

sudo apt-get -y install python-pip
sudo pip install docker-compose

尝试使用pip show --files docker-compose查看它的安装位置。

如果docker-compose安装在用户路径中，请尝试：

sudo "PATH=$PATH" docker-compose

正如我从你更新的帖子中看到的，docker-compose安装在用户路径/home/user/.local/bin中，如果此路径不在您的本地路径$PATH中，请尝试：

sudo "PATH=$PATH:/home/user/.local/bin" docker-compose
