标签：Name service py site 报错 usr pip requests packages
详细报错内容：
Traceback (most recent call last):

在我本地是不会出现该报错，部署在linux服务器运行项目就会出现该错误。
因为除了我在运用该台服务器还有别的技术人员在使用，requests版本落后导致的。
解决方法：更新requests 命令： pip install -U requests
如果出现下面报错：
ERROR: Cannot uninstall 'requests'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
使用distutils安装了某个包，你需要通过distutils来卸载这个包。不幸的是distutils不包含卸载命令，所以 "uninstall using distutils"就意味着你要手动移除这个包。
cd /usr/lib/python2.7/site-packages/
mkdir /opt/pylib_backup/
mv requests* /opt/pylib_backup/pip list 看到 requests包被卸载了
[root@bareos_server site-packages]# pip list |grep request
