我刚刚在lab环境中完成了dcos环境的安装，当我尝试在centos7 linux机器上安装dcos客户端时，我得到了
**[root@rmavmdock5 dcos]# bash install.sh . http://10.120.1.187**
Installing DC/OS CLI from PyPI...
New python executable in /root/dcos/bin/python
Installing setuptools, pip, wheel...done.
Traceback (most recent call last):

我查看了谷歌并发现我们的类似案例修复了运行“pip install futures”但即使在安装后安装仍然失败

点子版本
[root@rmavmdock5 bin]# pip -V
pip 8.1.2 from /root/dcos/lib/python2.7/site-packages (python 2.7)
逐行检查安装脚本我发现dcos客户端安装过程在安装脚本尝试运行时报告了这些错误
# storage dcos config set core.reporting true
但整个过程运行良好，直到使用命令配置 dcos 二进制文件
/root/dcos/bin/pip install --quiet dcoscli
，此命令是使 dcos 命令可用的命令，并且似乎由于任何原因无法正常工作
我使用 -v 选项运行了相同的命令（输出很大，不知道如何附加文件），但命令结束
