通过rpmbuild打包nova时，出现了如下报错：

  File "/usr/lib/python2.7/site-packages/keystoneauth2/session.py", line 26, in 
    import requests
  File "/usr/lib/python2.7/site-packages/requests/__init__.py", line 63, in 
    from . import utils
  File "/usr/lib/python2.7/site-packages/requests/utils.py", line 26, in 
    from .compat import (
ImportError: cannot import name integer_types

大致看了以下报错信息，应该是python的requests模块安装有问题，查看之前的依赖安装日志，出现过如下内容：

Failed:
  python2-requests.noarch 0:2.11.1-1.el7                                      python2-urllib3.noarch 0:1.16-1.el7

这两个模块安装失败，于是单独安装这两个模块，但是均报错

应该是这两个模块已存在的版本有问题，于是将site-packages中的这两个模块的内容删除

[root@localhost site-packages]# rm -rf url
urlgrabber/                     urllib3/                        urllib3-1.21.dist-info/         
urlgrabber-3.10-py2.7.egg-info  urllib3-1.16-py2.7.egg-info/
[root@localhost site-packages]# rm -rf urllib3*

[root@localhost site-packages]# rm -rf requests
requests/                                requestsexceptions/                      requests_mock/
requests-2.11.1-py2.7.egg-info/          requestsexceptions-1.1.3-py2.7.egg-info/ requests_mock-1.3.0.dist-info/

[root@localhost site-packages]# rm -rf requests
[root@localhost site-packages]# rm -rf requests-*

再安装模块即可成功

Complete!

再通过rpmbuild打包，就没有任何问题了。
