我们想执行一个包比较器，以将本地存储库中的Chocolatey包与公共存储库进行比较。现在，当我们执行剧本时，脚本的副本运行良好，但是脚本的执行也运行良好，但是由于某种原因而失败。也许其中一个可以帮助我呢？

 tasks:
    - name: Copy powershell file to Chocolatey server
      win_copy:
        src: ../powershell/package_comparer.ps1
        dest: C:\Temp\

    - name: Executing Powershell script
      win_shell: C:\Temp\package_comparer.ps1
      changed_when: false
      register: result

    - name: parse .json file
      set_fact:
         packages_result: "{{(result.stdout | from_json)}}"

    - debug:
        msg: "{{ packages_results }}"

我们可以执行此操作而不会出错。.现在我收到此错误：
