這幾天在安裝Jupyter Notebook 的時候，無論怎麼調，怎麼改編碼格式，都還是打不開Jupyter botebook,踩了很多坑，我的是Ubuntu 16.04系統。
先說一下我的安裝語句和步驟
（1）更新和升級包
sudo apt-get update sudo apt-get upgrade
（2）安裝pip sudo apt-get install python-pip
2. 安裝Jupyter
（1）升級pip sudo pip install --upgrade pip
（2）安裝Jupyter sudo pip install jupyter
錯誤如下！！！！！！！！！
1.有一個是什麼 未命名編碼錯誤，有什麼untitled什麼東西的。
2.wxy@wxy-ZHENGJIUZHE-REN7000-28ICB:~$ jupyter notebook
The Jupyter HTML Notebook.
這將啓動一個基於tornado的HTML筆記本服務器，它提供一個html5/
javascript筆記本客戶端。

一開始不知所措，在網上搜索也找不到解決方法，其中踩過最多的坑就是改編碼格式，不管是在/usr/local/lib/python2.7下邊建立sitecustomize.py還是在 /usr/lib/python2.7下邊修改sitecustomize.py，怎麼弄都不好使，網上給出的具體的修改方法就是在文件里加
import sys
reload(sys)
sys.setdefaultencoding(‘utf-8’)
統統沒用。
輸入以下命令：
sudo python3 -m pip install --upgrade pip
sudo python3 -m pip install jupyter
