【问题描述】：

在 Centos 上运行 DCOS 1.8。我安装了 CLI，如下所示： https://docs.mesosphere.com/1.8/usage/cli/install/

当我尝试进行 spark 安装时，出现以下错误。有什么想法吗？

./dcos package install spark

【问题讨论】：

我是 DC/OS CLI 的开发人员。你能粘贴./dcos --log-level=debug package install spark 和./dcos --version 的输出吗？谢谢！

另外，当我进入 DCOS 1.8 Web GUI 时，Universe -> Packages -> 出现错误。当我点击安装它说“无法连接服务器”

我刚遇到这个问题。对我来说，这是因为我忘了安装 virtualenv。 pip install virtualenv.
