UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 4: ordinal not in range (128)

deepin15.7桌面版

问题描述：

用系统自带的Python2.7在用sudo pip install jupyter notebook后启动jupyter notebook出现以下报错信息

报错信息：

sudo 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。

报错原因：

博主搜索了各大网站发现基本上都是说这是Python2.7的一个bug，凑巧我本来还就是想用Python2.7做实验的，无奈只有找用Python3.6（也是系统自带）的安装，找到如下解决方案

解决方案：

方案1：

• 先卸载当前安装的jupyter notebook

		sudo pip install pip-autoremove
		sudo pip-autoremove jupyter -y

• 用pip3（没有就安装一个）安装

		sudo pip3 install pip-autoremove

• 启动jupyter notebook

		jupyter notebook

方案2：

先安装anaconda，然后把anaconda的Python2.7设为系统默认使用的Python（有提示加入环境变量中），最后安装jupyter notebook. （可能会有小bug，比如启动后kernel崩坏，逃。。
