Question

在运行以下任务时，它给了我以下错误。我也检查了换行符和其他语法错误，但找不到一个。是否存在任何兼容性问题，或者我是否犯了任何愚蠢的语法问题？我正在未安装pip（且没有安装权限）的VM上运行此任务

   - name: Move old logs folder
     command: "mv {{ installed_dir }}/logs {{ installed_dir }}/logs_{{ old_version }}"  
     when: "groups['webservice'] | select('search','perfolab') | list"

错误消息：

fatal: [myserver.dm.com]: FAILED! => {"msg": "The conditional check 'groups['webservice'] | select('search','perfolab') | list' failed. The error was: template error while templating string: no filter named 'select'. String: {% if groups['webservice'] | select('search','perfolab') | list %} True {% else %} False {% endif %}\n\nThe error appears to have been in '/home/mylon/ansible-dep/webservice.yml': line 21, column 4, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n   - name: Move old logs folder\n     ^ here\n"}
