Question

我有ansible（v2.0.0.2）和python（v2.7.6），我正在运行'maven_artifact'模块。

作为一个直接的ansible命令，它工作正常

ansible localhost -m maven_artifact -a "group_id=commons-collections artifact_id=commons-collections dest=/tmp/commons-collections-latest.jar" -vvvv

但是当我通过剧本做同样的事情时

- name: download via maven
maven_artifact: group_id=junit artifact_id=junit dest=/tmp/junit-latest.jar

它因此错误而失败

fatal: [test01vm1]: FAILED! => {"changed": false, "failed": true, "invocation": {"module_name": "maven_artifact"}, 
"module_stderr": "", 
"module_stdout": "\r\nTraceback (most recent call last):\r\n  
File \"/home/admin123/.ansible/tmp/ansible-tmp-1454675562.75-201853614879442/maven_artifact\",
line 25, in <module>\r\n    from lxml import etree\r\nImportError: 
No module named lxml\r\n", "msg": "MODULE FAILURE", "parsed": false}

我相信可能与python lxml模块有关，我找到了这些现有的门票

我想知道有人可能有解决方法吗？

编辑 - 添加python路径详细信息

我运行此命令以查看python home上的路径

14:55:11@pcZBook-15:/usr/local/etc$ python -c 'import sys; print(":".join(sys.path))'

Answer 1

似乎ansible试图在远程目标主机上执行'maven_artifact'命令，该主机没有所需的python库。

在我的情况下，我只想在本地'ansible_host'上运行命令，所以我只是添加了'local_action'前缀并且命令运行。

- name: download via maven
  local_action: maven_artifact group_id=junit artifact_id=junit dest=/tmp/junit-latest.jar

Answer 2

我通常做的是致电：

- name: Install PIP
  apt: name=python-pip state=present

- name: Install lxml
  pip: name=lxml

Answer 3

只做

sudo apt-get install python -lxml
