error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/urllib3/packages/ssl_mat

        今天更新系统的时候出现了使用 yum 更新 python-urllib3 不成功的现象。

错误日志：

解决办法： 

        pip已经安装了对应的版本包，此时yum安装的rpm包与pip里的冲突，先把pip里的包卸载掉再用yum 重新安装

1. 查看是否用pip已经安装了urllib3
   

pip list |grep  urllib3

    2.  卸载pip安装的urllib3

pip uninstall urllib3

    3. 使用yum 更新

yum  update  python-urllib3

这样我的问题成功解决了。
