這期內容當中小編將會給大家帶來有關openstack nova編譯或打包rpm出現cannot import name integer_types報錯的解決方法，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。
通過rpmbuild打包nova時，出現了如下報錯：
File "/usr/lib/python2.7/site-packages/keystoneauth2/session.py", line 26, in <module> import requests File "/usr/lib/python2.7/site-packages/requests/__init__.py", line 63, in <module> from . import utils File "/usr/lib/python2.7/site-packages/requests/utils.py", line 26, in <module> from .compat import ( ImportError: cannot import name integer_types
大致看了以下報錯信息，應該是python的requests模塊安裝有問題，查看之前的依賴安裝日志，出現過如下內容：
Failed: python2-requests.noarch 0:2.11.1-1.el7 python2-urllib3.noarch 0:1.16-1.el7
這兩個模塊安裝失敗，于是單獨安裝這兩個模塊，但是均報錯
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
應該是這兩個模塊已存在的版本有問題，于是將site-packages中的這兩個模塊的內容刪除
[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-*
再安裝模塊即可成功
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!
再通過rpmbuild打包，就沒有任何問題了。
