以下任务在我的机器上直接运行时工作正常。 当我通过SSH从远程计算机上运行它时，它会永久挂起。
这是任务：
- name: deploy public directory synchronize: src="{{ my_root_path }}/.deploy/office/public/" dest="{{ my_root_path}}/office/public/" compress=no checksum=yes delete=yes recursive=yes times=yes links=yes archive=no rsync_opts=--no-motd,--exclude=.gitignore delegate_to: "{{ inventory_hostname }}" 这是挂起之前的输出：

任何可能出错的想法？
经过一番调查后发现问题与代理转发有关。 向ssh_args中的ssh_args设置添加-o ForwardAgent = yes就行了。
