在Win7下的python3.8环境下安装jupyter notebook

本机系统是WIN7，所以最新版只能安装python3.8.6版，想安装个Jupyter使用，在运行CMD的终端下，运行pip install jupyter，结果出现如下提示：

于是安装个Anaconda3-2019.10-Windows-x86_64版本，这版本自带python3.7及jupyter，但启动jupyter后，它也就启动python3.7，当我用PIP安装pip install openyxl、pip install xlwt、pip install requests这类程序后，它是安装在python3.8下面的，对于这个jupyter的import中使用报错，说没安装对应程序！没法只有删除Anaconda！
后在网上查询到只有用下面PIP安装方法才可安装jupyter:

先把PIP升级：

pip install pip --upgrade pip

再安装jupyter:
