尝试运行命令“ansible -m ping uat”时出现错误，但我可以通过跳转服务器从主机 ssh 到远程服务器。

我用 Mitogen 来加速。请查看使用 -vvv 运行 ansible ping 命令时获取的以下日志。

以下是日志：

这是一个不寻常的问题。如果您已建立成功的 SSH 连接，则不应发生这种情况。确保所有主机都添加到您尝试 ping 的清单文件中或尝试在清单文件中添加插件，启用 ini 插件。enable_plugins = ini

我可以看到一些 mitogen 条目您是否在默认设置中使用 mitogen 作为 strategy_plugin？建议尝试在您的 ansible.cfg 文件中评论 (strategy_plugin, strategy)。

从日志的外观来看，您似乎正在运行 Ansible 版本 2.9.9。Mitogen 0.2.9 版似乎适用于 Ansible 2.3-2.8 以及 Python 2.6、2.7、3.6 和 3.7

验证 Mitogen 版本并尝试在 ansible.cfg 文件中对其进行注释
