win下安裝jupyter遇到的問題

一：安裝jupyter

　　1、首先要用管理員方式打開cmd，沒用管理員打開后面安裝不上。

　　2、安裝jupyter。我用的是python3，所以用pip3 install jupyter進行安裝。

　　3、安裝完后打開jupyter。cmd下輸入jupyter notebook。

 

我第一次安裝jupyter遇到好多問題：首先爆出ModuleNotFoundError: No module named 'markupsafe' 沒有找到markupsafe模塊

C:\Windows\system32>jupyter notebook
Traceback (most recent call last):
  File "c:\users\felix\appdata\local\programs\python\python36\lib\runpy.py", line 193, in _run_module_as_main

    from markupsafe import Markup, escape, soft_unicode
ModuleNotFoundError: No module named 'markupsafe'

剛開始我在cmd下輸入pip3 install markupsafe嘗試安裝缺少的模塊。爆出了編碼錯誤，嘗試改變終端的編碼方式，折騰了半天沒解決編碼問題。最后通過git bash安裝成功解決

C:\Windows\system32>pip3 install markupsafe

首先打開Git Bash，在Git Bash下輸入 pip3 install markupsafe，成功安裝。接下來運行jupyter，成功運行。如果沒有安裝Git Bash -->安裝git

$ pip3 install markupsafe

總結：感覺這個問題確實是編碼的問題導致的，終端的字符編碼會影響 pip 安裝 Python 庫。
