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, inimport 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
Downloading packages: (1/2): python2-urllib3-1.16-1.el7.noarch.rpm | 126 kB 00:00:00 (2/2): python2-requests-2.11.1-1.el7.noarch.rpm | 105 kB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------- Total 190 kB/s | 231 kB 00:00:01 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : python2-urllib3-1.16-1.el7.noarch 1/2 Error unpacking rpm package python2-urllib3-1.16-1.el7.noarch error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname: cpio: rename Installing : python2-requests-2.11.1-1.el7.noarch 2/2 Error unpacking rpm package python2-requests-2.11.1-1.el7.noarch error: python2-urllib3-1.16-1.el7.noarch: install failed error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/requests/packages/chardet: cpio: rename Verifying : python2-urllib3-1.16-1.el7.noarch 1/2 Verifying : python2-requests-2.11.1-1.el7.noarch 2/2 Failed: python2-requests.noarch 0:2.11.1-1.el7 python2-urllib3.noarch 0:1.16-1.el7
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/ requests-2.13.0.dist-info/ requestsexceptions-1.2.0.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
Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : python2-urllib3-1.16-1.el7.noarch 1/2 Installing : python2-requests-2.11.1-1.el7.noarch 2/2 Verifying : python2-urllib3-1.16-1.el7.noarch 1/2 Verifying : python2-requests-2.11.1-1.el7.noarch 2/2 Installed: python2-requests.noarch 0:2.11.1-1.el7 Dependency Installed: python2-urllib3.noarch 0:1.16-1.el7 Complete!
再通过rpmbuild打包，就没有任何问题了。
