我在 CentOS 6.5 上安装 Ansible 时出现OSError：[Errno 2] 没有该文件或目录

[batandwa@localhost ansible]$ ansible-playbook -i hosts main.yml -v
 [WARNING]: The version of gmp you have installed has a known issue regarding

OSError: [Errno 2] No such file or directory

我运行的文件夹包含主办方，主目录和变量.yml。

甚至ansible -i hosts all -m ping不起作用并返回相同的错误。

基于对 Google 上的 Ansible 项目组的评论，安装openssh 客户端为我修复了这个问题：

sudo yum install openssh-clients

Answer 2

这是 CentOS 6 上的 EPEL 软件包的一个问题。它是 ansible 依赖项的一个旧依赖项，如果升级可能会破坏其他东西，因此不确定 EPEL 中是否会对此采取任何措施。
