我是在ubuntu中，自带的有python2,python3有安装了anaconda套件，所以python的版本很多，曾经想删除过不用的python．
先执行
sudo apt remove python*在想安装anaconda，结果悲剧了，xorg没有了，结果只能ｃｍｄ玩耍了，一气之下重装ubuntu18系统了

估计解决不了了，不折腾，采用自带python测试一下．
终于找到bug了，应该是代理服务的鬼
在使用wegt下载的时候发现的
dflx@dflx:~$ wget https://bootstrap.pypa.io/get-pip.py
--2018-06-22 16:37:01-- https://bootstrap.pypa.io/get-pip.py
正在连接 127.0.0.1:8888... 失败：拒绝连接。使用netstat查看本地端口的使用情况
dflx@dflx:~$ sudo netstat -ntpl
激活Internet连接 (仅服务器)

发现并没有服务在占用端口8888
查看本地网络是否走了代理服务
dflx@dflx:~$ export | grep -i prox
declare -x ftp_proxy=""
declare -x http_proxy="127.0.0.1:8888"
declare -x https_proxy="127.0.0.1:8888"
declare -x socks_proxy=""在找到了被占用的端口的8888， 确实是走了代理，于是问题找到了。
关闭服务
dflx@dflx:~$ unset https_proxy
dflx@dflx:~$ export | grep -i prox
declare -x ftp_proxy=""
declare -x http_proxy="127.0.0.1:8888"
declare -x socks_proxy=""测试selenium，可以使用
