我有以下 yaml ansible-playbook 并希望传输 rpm，然后将它们本地安装到远程机器上。直到传输文件步骤它工作正常但是在安装部分我出现以下错误："Failure talking to yum: near \"gskcrypt64\": syntax error" 知道如何克服这部分吗？

Ansible 版本：

ansible 2.4.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
   ansible python module location = /usr/lib/python2.7/site-packages/ansible
   executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Jun 11 2019, 12:19:05) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]

Ansible 剧本：

---
- hosts: "1.2.3.4"
  connection: "ssh"
  vars:
    RPM: 
    - gskcrypt64-8.0.50.86.linux.ppcle.rpm 
    - gskssl64-8.0.50.86.linux.ppcle.rpm 
    - TIVsm-API64.ppc64le.rpm 
    - TIVsm-BA.ppc64le.rpm
  tasks:
   - name: "Transfer Files"
     copy: src=/root/ansible_playbooks/{{ item }} dest=/root/
     with_items: "{{ RPM }}"
   - name: "Install Local RPMs"
     shell: yum localinstall -y /root/*.rpm

如果我更改 shell 模块，则会报告相同的错误

   - name: "Install Local RPMs"
     yum:
      name: /root/{{ RPM }}
      state: present

错误：

root@server [/root/ansible_playbooks] > ansible-playbook tsm

Edit1：我尝试了以下循环，因为文件已经在另一边：

---
- hosts: "1.2.3.4"
connection: "ssh"
vars:
RPM:
- gskcrypt64-8.0.50.86.linux.ppcle.rpm
- gskssl64-8.0.50.86.linux.ppcle.rpm
- TIVsm-API64.ppc64le.rpm
- TIVsm-BA.ppc64le.rpm
tasks:
- name: "Install Local RPMs"
yum:
name: /root/"{{ item }}"
state: present
loop: "{{ RPM }}"

现在收到以下错误：

fatal: [1.2.3.4]: FAILED! => {"msg": "Unexpected failure in finding the lookup named '{{ RPM }}' in the available lookup plugins"}

编辑2：

尝试移动并测试 yum localinstall 的失败部分：

  ---
- hosts: "1.2.3.4"
  connection: "ssh"
  vars:
    RPM:
    - gskcrypt64-8.0.50.86.linux.ppcle.rpm
    - gskssl64-8.0.50.86.linux.ppcle.rpm
    - TIVsm-API64.ppc64le.rpm
    - TIVsm-BA.ppc64le.rpm
  tasks:
   - name: "Install Local RPMs"
     yum:
      name: "/root/{{RPM}}"
      state: present

但得到错误：

fatal: [1.2.3.4]: FAILED! => {"changed": false, "msg": "Failure talking to yum: near \"gskcrypt64\": syntax error"}

我正在设置几个 ulimit（系统是 rhel 7.5），但我找不到任何关于type. 从内部/etc/security/limits.conf我得到该类型可以获取两个值，而在配置示例中该文件包含有 3 个值：

1. 柔软的
2. 难的
3. - （破折号）

在@students下面的文件示例中，有一个类型-。

何时使用- （破折号）？

    ....
    #<type> can have the two values:
    #        - "soft" for enforcing the soft limits
    #        - "hard" for enforcing hard limits
    .....
    #<domain>      <type>  <item>         <value>
    #*               soft    core            0
    #*               hard    rss             10000
    #@student        hard    nproc           20
    #@faculty        soft    nproc           20
    #@faculty        hard    nproc           50
    #ftp             hard    nproc           0
    #@student        -       maxlogins       4
    .....
