openstack nova編譯或打包rpm出現(xiàn)cannot import name integer_types報(bào)錯(cuò)的解決方法

這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)?lái)有關(guān)openstack nova編譯或打包rpm出現(xiàn)cannot import name integer_types報(bào)錯(cuò)的解決方法，文章內(nèi)容豐富且以專業(yè)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(guò)rpmbuild打包nova時(shí)，出現(xiàn)了如下報(bào)錯(cuò)：

  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(bào)錯(cuò)信息，應(yīng)該是python的requests模塊安裝有問(wèn)題，查看之前的依賴安裝日志，出現(xiàn)過(guò)如下內(nèi)容：

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

這兩個(gè)模塊安裝失敗，于是單獨(dú)安裝這兩個(gè)模塊，但是均報(bào)錯(cuò)

應(yīng)該是這兩個(gè)模塊已存在的版本有問(wèn)題，于是將site-packages中的這兩個(gè)模塊的內(nèi)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/

再安裝模塊即可成功

Complete!

再通過(guò)rpmbuild打包，就沒(méi)有任何問(wèn)題了。
