无法在Mac OSX上安装dcos-cli

Question

DCOS提供了以下安装命令来安装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

然而，当我在我的Mac上运行它时，它失败了，并显示以下信息：

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？

我所看到的大多数关于在OS上安装DC/OS的问题都有一个与prerequisites未满足相关的根本原因。也就是说，在DC/OS1.8中，我们引入了用于命令行界面的binaries (正是为了避免您所描述的情况)。
