尝试在远程EC2主机上执行ansible剧本。执行命令时出现错误

Question

我有一个剧本文件，其中包含以下简单命令。 ansible版本2.8.1已安装在远程主机上。

剧本文件：

---
- name: Deploy accounts on AWS staging
  gather_facts: False
  hosts: Project_stage
  roles:
    - { role: stageRole }

角色stageRole的任务文件：

---
- name: Deploying WAR on EB
  command: eb --version chdir=/opt/EB_accounts

在执行上述剧本后，我可以看到以下异常，错误消息为“ msg”：“ [Errno 2]没有这样的文件或目录”，

例外：

host_web02 (0, '', '')
