由于每台机器的环境都不尽相同,存在某些机器的yum源太小或者所带软件版本太低或缺失等问题,所以在安装软件时也可能会产生不同的依赖报错。下面我就以安装ansible时自身遇到过的依赖问题解决方法作介绍,只介绍解决依赖部分内容,安装ansible详细过程另请自行百度。
一、 使用ansible --version

Ansible并未安装完成,存在依赖问题。

附报错内容:
ERROR! Unexpected Exception, this is probably a bug: (cryptography 1.3.1 (/usr/lib64/python2.7/site-packages), Requirement.parse(‘cryptography>=1.5‘))
the full traceback was:

VersionConflict: (cryptography 1.3.1 (/usr/lib64/python2.7/site-packages), Requirement.parse(‘cryptography>=1.5‘))

估计是cryptography该模块的问题(版本太低)。

  1. 安装cryptography前先安装setuptools

    这里Setuptools版本需要大于等于18.5.

  2. 解压安装
    技术图片
    #python setup.py build
    #python setup.py install

  3. 安装cffi(在安装cryptography之前报错,应该先安装cffi)
    [root@zabbix-server cryptography-2.8]# python setup.py install
    Download error on https://pypi.python.org/simple/cffi/: [Errno -2] Name or service not known -- Some packages may not be found!

    File "build/bdist.linux-x86_64/egg/setuptools/command/easy_install.py", line 632, in easy_install

distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse(‘cffi!=1.11.3,>=1.8‘)

安装cffi
l python setup.py build
l python setup.py install

还是缺包

又报错(估计还是缺包)

该图片中报错关于Python.h的,并未找到相应的文件或目录,直接安装python3.4-devel,即可解决
yum install python-devel #因为我这ansible是用2版本的,所以后面装python-devel,python不带数字默认装2版本。

  1. 上传cryptography

    解压安装
    技术图片
    #python setup.py build
    #python setup.py install

  2. 解决问题,成功得到版本信息

看到这里能够成功获取到ansible的版本信息则说明ansible已经安装成功了。
