python之ansible 剧本 : No package matching 'python-pip' found available -on centos guest 出错

我正在尝试通过 Ansible 剧本在 centos guest(通过 vagrant 旋转)上安装一些软件包。这是我尝试安装的片段

- name: Installing helpful tools and packages 
   yum: 
    pkg: "{{ item }}" 
    state: present 
  with_items: 
    - ntp 
    - tcpdump 
    - policycoreutils-python 
    - vim 
    - vim-X11 
    - yum-utils 
    - deltarpm 
    - git 
    - ntp 
    - python-pip 
    - pip 
  when: 
    - ansible_os_family == "RedHat" 
 
- name: Install shade using pip. 
  #become: yes 
  pip: 
    name: "{{ item }}" 
    state: present 
  with_items: 
    - pip 
    - shade 

这是我收到的错误。无法获取“python-pip”

请您参考如下方法:

我相信您列表中的所有内容都可以从默认的 RHEL/CentOS 存储库中获得，除了 python-pip，我认为您必须从 EPEL 获得它。您是否在远程系统上配置并启用了 EPEL 存储库？
