dcos - 无法在 Mac OSX 上安装 dcos-cli

Question

DCOS提供如下安装命令来安装cli工具:

mkdir -p dcos && cd dcos && 
curl -O https://downloads.dcos.io/dcos-cli/install.sh && 
bash ./install.sh . https://mydomain.co && 
source ./bin/env-setup

但是，当我在我的 Mac 上运行它时，它失败并显示以下内容:

mkdir -p dcos && cd dcos &&
 | →   curl -O https://downloads.dcos.io/dcos-cli/install.sh &&
 | →   bash ./install.sh . https://mydomain.co &&
 | →   source ./bin/env-setup

当我在 Ubuntu 上运行相同的命令时，它工作得很好。知道根本原因是什么吗？

我在 OS X 上安装 DC/OS CLI 时遇到的大多数问题都有一个与 prerequisites 相关的根本原因。没见过。也就是说，在 DC/OS 1.8 中我们引入了 binaries对于 CLI(正是为了避免您描述的情况)。
