Ansible-模板-“字典对象”没有属性“ stdout_lines”

Question

我正在使用Asible-2.4.5.0

尝试将安装的yum list的结果插入模板生成的文件时出现问题。我收到以下错误：

 'dict object' has no attribute 'stdout_lines'

这是任务

- name: Capture output of currently installed RPMs
  yum:
    list=installed
  register: yum_list_installed
- debug:
   msg: " {{ yum_list_installed }} "
- template:
    src: yumlistinstalled.j2
    dest: /var/tmp/{{backupDir}}/yum_list_installed

这是我的模板文件。

{% for i in yum_list_installed.stdout_lines  %}
{{ i }}
{% endfor %}

我的屏幕上的调试输出显示信息没有问题。问题是当我尝试将数据插入模板生成的文件中时。下面是输出示例。
