[已解决]Ubuntu16.04安装jupyter notebook的编码问题，怎么修改都不行

这几天在安装Jupyter Notebook 的时候，无论怎么调，怎么改编码格式，都还是打不开Jupyter botebook,踩了很多坑，我的是Ubuntu 16.04系统。

先说一下我的安装语句和步骤

（1）更新和升级包

sudo apt-get update sudo apt-get upgrade

（2）安装pip sudo apt-get install python-pip

2. 安装Jupyter

（1）升级pip sudo pip install --upgrade pip

（2）安装Jupyter sudo pip install jupyter

错误如下！！！！！！！！！

1.有一个是什么未命名编码错误，有什么untitled什么东西的。

2.wxy@wxy-ZHENGJIUZHE-REN7000-28ICB:~$ jupyter notebook
The Jupyter HTML Notebook.

这将启动一个基于tornado的HTML笔记本服务器，它提供一个html5/
javascript笔记本客户端。

Traceback (most recent call last):

sys.exit(main())

一开始不知所措，在网上搜索也找不到解决方法，其中踩过最多的坑就是改编码格式，不管是在/usr/local/lib/python2.7下边建立sitecustomize.py还是在 /usr/lib/python2.7下边修改sitecustomize.py，怎么弄都不好使，网上给出的具体的修改方法就是在文件里加

import sys

reload(sys)

sys.setdefaultencoding(‘utf-8’)
