Question

我正在尝试将Ansible与几个CoreOS虚拟机一起使用。我安装了ActivePython，系统识别二进制文件。当我尝试使用内置的Ansible模块（ping）进行测试时，会抛出以下错误：

deploy@kube-bh:~$ ansible dhcp-coreos155 -m ping
dhcp-coreos155 | FAILED! => {
    "changed": false, 
    "failed": true, 
    "module_stderr": "Shared connection to dhcp-coreos155 closed.\r\n", 
    "module_stdout": "/bin/sh: -c: line 0: unexpected EOF while looking for matching `\"'\r\n/bin/sh: -c: line 1: syntax error: unexpected end of file\r\n", 
    "msg": "MODULE FAILURE", 
    "rc": 1
}

有趣的是，如果我使用-m raw运行Ansible命令，则会成功：

deploy@kube-bh:~$ ansible dhcp-coreos155 -m raw -a 'uptime'
dhcp-coreos155 | SUCCESS | rc=0 >>
 20:02:21 up 1 day, 22:11,  2 users,  load average: 0.00, 0.00, 0.00
Shared connection to dhcp-coreos155 closed.

我在失败命令上使用-vvvv标志来查看连接状态，看来SSH正在正确连接到CoreOS节点。我收集了更多信息，但为什么错误发生并不清楚。

对我来说，看起来你已经在某处弄乱了Python可执行文件定义（你不显示配置，它可能是Ansible清单或ansible.cfg） - 存在不平衡的报价命令Ansible中的标记执行：

 /home/deploy/bin/python"

Shell打开一个引号，但在找到匹配的右引号之前，整个命令结束，因此它会抛出一个意外的EOF找到的异常。

raw模块没有调用Python，因此没有错误。

Ansible错误：/ bin / sh：-c：第0行：寻找匹配时意外的EOF“
