防止错误-没有模块名为packaging.version

Question

我有CentOS7.3和AnbleVersion2.3。

Ansible 2.3.0.0
config file = ../ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.5 (default, Nov  6 2016, 00:28:07) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

我需要在Azure VM中运行ansible剧本。

运行时，我会得到以下错误

fatal: [52.170.201.24]: FAILED! => {"changed": false, "failed": true, "module_stderr": "Shared connection to 52.170.201.24 closed.\r\n", 
"module_stdout": "\r\nTraceback (most recent call last):\r\n  File \"/tmp/ansible_k2CnFR/ansible_module_azure_rm_virtualmachine.py\", line 445, in <module>\r\n    
from ansible.module_utils.azure_rm_common import *\r\n  
File \"/tmp/ansible_k2CnFR/ansible_modlib.zip/ansible/module_utils/azure_rm_common.py\", line 29, in <module>\r\nImportError: No module named packaging.version\r\n", "msg": "MODULE FAILURE", "rc": 0}

尝试安装setuptools，如几个站点所示

sudo pip install setuptools
Requirement already satisfied: setuptools in /root/.local/lib/python2.7/site-packages
Requirement already satisfied: six>=1.6.0 in /root/.local/lib/python2.7/site-packages (from setuptools)
Requirement already satisfied: appdirs>=1.4.0 in /root/.local/lib/python2.7/site-packages (from setuptools)
Requirement already satisfied: packaging>=16.8 in /root/.local/lib/python2.7/site-packages (from setuptools)
Requirement already satisfied: pyparsing in /root/.local/lib/python2.7/site-packages (from packaging>=16.8->setuptools

尝试如几个站点中提到的那样升级pip，并将其升级到最新版本。

pip -V
pip 9.0.1 from /usr/lib/python2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

which pip
/usr/bin/pip
$ which pip3
/usr/local/bin/pip3
$ which python
/usr/bin/python

更新：

42.170.201.24是Azure虚拟机的IP地址，它是库存主机的一部分。

实际上，我正在尝试在Azure虚拟机上使用我的无意义控制计算机中的这个无意义代码来供电。

- name: Power On Docker repo if Azure
  azure_rm_virtualmachine:
    resource_group: HpsaPoc
    name: DockerRepo
    started: yes
  when:  "{{cloud_provider}}" == 'azure'

我无法理解这个python/pip配置，我尝试过安装python3.5和pip3，但是没有帮助，所以删除了它，因为我不知道如何卸载它。请帮帮忙。

Answer 1

似乎您试图从远程主机执行azure_rm_virtualmachine，而不是从您的Ansible控件主机执行。

尝试：

- name: Power On Docker repo if Azure
  azure_rm_virtualmachine:
    resource_group: HpsaPoc
    name: DockerRepo
    started: yes
  when: cloud_provider == 'azure'
  delegate_to: localhost

Answer 2

发生上述错误是因为您的环境没有打包模块。

通过安装封装模块来解决这个问题。

pip安装包装

上述命令将安装16.8版本的打包模块。
